Ovarian Torsion: Causes, Symptoms, Diagnosis & Treatment Guide
Introduction
Ovarian torsion is a serious medical condition that occurs when an ovary twists around the ligaments that support it, cutting off its blood supply. This gynecological emergency requires prompt medical attention to prevent complications such as tissue death or the potential loss of the ovary. First documented in the 19th century, ovarian torsion remains a rare but significant diagnosis. This article provides a detailed overview of ovarian torsion, including its risk factors, symptoms, diagnostic methods, treatment options, and self-care strategies. By understanding this condition, you can recognize its warning signs early and seek timely care, which may help preserve ovarian function and prevent long-term complications.
What is Ovarian Torsion?
Ovarian torsion occurs when an ovary twists around its supporting structures, restricting blood flow. This article delves into its risk factors, symptoms, diagnostic tools, medical and surgical treatments, and strategies for managing symptoms at home.
Description of Ovarian Torsion
Ovarian torsion happens when the ovary twists around the ligaments that hold it in place, often involving the fallopian tube as well. This twisting disrupts blood flow, leading to intense pain and potential damage to the ovarian tissue. The condition is frequently associated with ovarian cysts or masses, which can increase the ovary’s weight and make it more prone to twisting. Although ovarian torsion can occur at any age, it is most commonly seen in women of reproductive age.
If left untreated, the lack of blood flow can result in tissue death (necrosis), which may lead to infection, infertility, or the need for surgical removal of the ovary. Early diagnosis and treatment are essential to avoid these complications.
Ovarian torsion accounts for approximately 3% of all gynecological emergencies and is more common in women with risk factors such as ovarian cysts or a history of pelvic surgeries. While rare, it requires immediate medical attention, as delays in treatment can lead to severe outcomes.
Risk Factors for Developing Ovarian Torsion
Lifestyle Risk Factors
Although ovarian torsion is primarily influenced by medical and anatomical factors, certain lifestyle choices may indirectly increase the risk. High-impact physical activities or sudden movements can contribute to ovary twisting in women with predisposing factors like ovarian cysts. On the other hand, a sedentary lifestyle may lead to obesity, which is associated with a higher likelihood of ovarian cyst formation—a known risk factor for torsion.
Maintaining a healthy weight and engaging in regular physical activity can help reduce the risk of conditions that predispose women to ovarian torsion. However, it is important to note that lifestyle changes alone cannot completely eliminate the risk.
Medical Risk Factors
Several medical conditions can increase the likelihood of ovarian torsion. Large ovarian cysts are a common risk factor, as are conditions like polycystic ovary syndrome (PCOS), which is characterized by multiple small cysts on the ovaries. Women undergoing fertility treatments, such as ovarian stimulation, are also at higher risk due to the enlargement of the ovaries during these procedures.
Pregnancy is another contributing factor, as hormonal changes and ovary enlargement in early pregnancy can increase susceptibility to twisting. Additionally, a history of pelvic or abdominal surgeries may result in scar tissue (adhesions), which can alter the positioning of the ovaries and raise the risk of torsion.
Genetic and Age-Related Risk Factors
Ovarian torsion is most frequently observed in women aged 20 to 40, likely due to the prevalence of ovarian cysts and hormonal fluctuations during this stage of life. However, it can also occur in postmenopausal women and children, though these cases are less common.
Genetic predispositions, such as a family history of ovarian cysts or other gynecological conditions, may also increase the risk. While these factors cannot be controlled, being aware of your family medical history can help you and your healthcare provider monitor for early warning signs.
Clinical Manifestations of Ovarian Torsion
Abdominal Pain
Abdominal pain is the most common symptom of ovarian torsion, reported in 90-100% of cases. The pain is typically sudden, severe, and localized to one side of the lower abdomen or pelvis. This occurs because the twisting of the ovary cuts off its blood supply, leading to ischemia (tissue damage). The pain may intensify over time if the torsion persists and can radiate to the back or thigh. Patients often describe the pain as sharp or stabbing, with little to no relief from position changes or over-the-counter pain medications.
Nausea
Nausea is experienced in 50-70% of ovarian torsion cases. It often accompanies severe abdominal pain and is thought to result from the body’s response to pain and reduced blood flow. The twisting of the ovary may also irritate nearby structures, such as the gastrointestinal tract, contributing to nausea. Additionally, stress and anxiety caused by acute pain can further worsen this symptom.
Vomiting
Vomiting occurs in 50-60% of patients with ovarian torsion. It is typically a reaction to severe pain and the body’s stress response. Vomiting may persist without providing relief and can lead to dehydration, complicating the overall clinical picture. Patients experiencing vomiting alongside other symptoms, such as abdominal pain, should seek immediate medical care.
Unilateral Pelvic Pain
Unilateral pelvic pain, or pain on one side of the pelvis, is reported in 70-90% of cases. This symptom arises because ovarian torsion usually affects only one ovary. The pain is sharp, localized, and often accompanied by tenderness. Identifying the side of the pain can help healthcare providers determine which ovary is affected. If the torsion resolves spontaneously, the pain may subside temporarily, but recurrence is likely without treatment.
Fever
Fever is observed in 10-20% of ovarian torsion cases, particularly when tissue necrosis has occurred. It signals inflammation or infection due to prolonged ischemia. While not a primary symptom, fever in combination with severe pain and vomiting may indicate advanced torsion. Patients experiencing fever alongside other symptoms should seek urgent medical attention.
Tachycardia
Tachycardia, or an elevated heart rate, occurs in 15-25% of cases. It is often a response to severe pain and stress, as the sympathetic nervous system becomes activated. Dehydration from vomiting or significant blood loss can also contribute to tachycardia. Persistent tachycardia requires immediate medical evaluation, as it may indicate worsening conditions.
Abdominal Tenderness
Abdominal tenderness is present in 60-80% of ovarian torsion cases. This refers to pain or discomfort when the abdomen is pressed. Tenderness is usually localized to the affected ovary and results from inflammation and irritation of surrounding tissues. When combined with other symptoms like severe pain and nausea, abdominal tenderness can help narrow down the diagnosis.
Altered Bowel Habits
Altered bowel habits, such as constipation or diarrhea, are reported in 10-15% of patients. These symptoms occur when the twisted ovary presses against the bowel, disrupting its function. Inflammation and irritation caused by torsion can also affect nearby organs, including the intestines. While not specific to ovarian torsion, altered bowel habits alongside other symptoms may raise suspicion for this condition.
Urinary Symptoms
Urinary symptoms, such as frequent urination or difficulty urinating, occur in 5-10% of cases. These symptoms result from the ovary’s proximity to the bladder. When the ovary twists, it can press on the bladder, causing discomfort or changes in urinary habits. Although less common, urinary symptoms can provide additional diagnostic clues.
Adnexal Mass
An adnexal mass, or a lump near the ovary, is identified in 50-60% of patients during imaging or physical exams. This mass is often a cyst or tumor that predisposed the ovary to torsion. Larger masses increase the risk of torsion by making the ovary heavier and more likely to twist. Detecting an adnexal mass is crucial for confirming the diagnosis and planning treatment.
Diagnostic Evaluation
How is Ovarian Torsion Diagnosed?
Ovarian torsion is primarily diagnosed based on symptoms and findings from a physical examination. However, imaging studies and laboratory tests are essential for confirmation and to rule out other conditions. Diagnosis typically begins with an ultrasound, the most commonly used imaging tool. Blood tests and urinalysis may also be performed to assess overall health and identify potential complications. In some cases, laparoscopy—a minimally invasive surgical procedure—may be necessary for a definitive diagnosis and treatment. Early diagnosis is critical to prevent permanent ovarian damage.
Ultrasound
Test Information: Ultrasound uses high-frequency sound waves to create images of internal organs. For ovarian torsion, transabdominal or transvaginal ultrasound is performed to visualize the ovaries and surrounding structures. This non-invasive test typically takes 20-30 minutes and helps identify the size, shape, and position of the ovaries, as well as any adnexal masses or cysts.
Results that Indicate Ovarian Torsion: Key findings include an enlarged ovary, free pelvic fluid, and the presence of an adnexal mass. The “whirlpool sign,” which indicates a twisted vascular pedicle, is a hallmark feature. If ultrasound findings are inconclusive but symptoms persist, further imaging may be necessary.
Doppler Ultrasound
Test Information: Doppler ultrasound evaluates blood flow to the ovaries by measuring blood movement through vessels. Often performed alongside standard ultrasound, this painless test takes about 15-20 minutes and is particularly useful for assessing compromised blood supply.
Results that Indicate Ovarian Torsion: Reduced or absent blood flow strongly suggests ovarian torsion. However, normal blood flow does not entirely rule out torsion, as intermittent twisting can temporarily restore circulation. Inconclusive findings may require additional imaging or surgical exploration.
What if All Tests are Negative but Symptoms Persist?
If diagnostic tests are negative but symptoms persist, continued medical evaluation is essential. Persistent symptoms may warrant repeat testing or consultation with a specialist. In some cases, exploratory laparoscopy may be necessary to directly visualize the ovaries and confirm or rule out torsion. Early intervention is vital to prevent complications, so ongoing symptoms should never be ignored.
Health Conditions with Similar Symptoms to Ovarian Torsion
Ectopic Pregnancy
An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in a fallopian tube. This condition is a medical emergency because the growing pregnancy can rupture the tube, leading to severe internal bleeding. Symptoms often include sharp pelvic or abdominal pain, vaginal bleeding, and dizziness or fainting.
How to Differentiate Ectopic Pregnancy from Ovarian Torsion
Both ectopic pregnancy and ovarian torsion can cause sudden, intense lower abdominal or pelvic pain. However, vaginal bleeding is a key symptom of ectopic pregnancy and is not typically associated with ovarian torsion. Additional symptoms like dizziness, fainting, or shoulder pain (caused by internal bleeding) are more common in ectopic pregnancy.
Healthcare providers may use a pregnancy test to help distinguish between the two. A positive test, combined with a transvaginal ultrasound showing an empty uterus or a mass in the fallopian tube, confirms ectopic pregnancy. In contrast, ovarian torsion is identified through imaging that reveals an enlarged ovary or disrupted blood flow. If you experience severe pain, seek immediate medical attention.
Pelvic Inflammatory Disease (PID)
Pelvic inflammatory disease (PID) is an infection of the female reproductive organs, often caused by sexually transmitted infections (STIs) such as chlamydia or gonorrhea. PID can lead to chronic pelvic pain, fever, unusual vaginal discharge, and discomfort during intercourse or urination. If left untreated, it may result in infertility or other serious complications.
How to Differentiate PID from Ovarian Torsion
While both PID and ovarian torsion can cause pelvic pain, PID is more likely to present with fever, foul-smelling vaginal discharge, and pain during intercourse—symptoms not typically seen with ovarian torsion.
To diagnose PID, healthcare providers may perform a pelvic exam to check for tenderness, along with STI tests, blood tests, or an ultrasound. Imaging for ovarian torsion often shows an enlarged ovary or disrupted blood flow, while PID may reveal inflammation or abscesses. Early treatment is essential for both conditions, so consult a healthcare provider if you suspect either.
Ruptured Ovarian Cyst
An ovarian cyst is a fluid-filled sac that forms on or inside the ovary. While most cysts are harmless and resolve on their own, a ruptured cyst can cause sudden, sharp pelvic pain. Other symptoms may include bloating, nausea, and light vaginal bleeding.
How to Differentiate a Ruptured Ovarian Cyst from Ovarian Torsion
Both conditions can cause sudden, severe pelvic pain, but a ruptured ovarian cyst may also involve light vaginal bleeding or spotting, which is uncommon in ovarian torsion. Additionally, pain from a ruptured cyst may gradually improve, whereas torsion pain typically worsens over time.
Healthcare providers may use a pelvic ultrasound to differentiate between the two. A ruptured cyst often appears as fluid in the pelvis, while ovarian torsion is more likely to show an enlarged ovary with reduced or absent blood flow. If you experience sudden, severe pain, seek immediate medical care.
Appendicitis
Appendicitis is the inflammation of the appendix, a small pouch attached to the large intestine. It is a medical emergency that typically causes pain in the lower right abdomen, along with nausea, vomiting, and fever. If untreated, the appendix can rupture, leading to life-threatening complications.
How to Differentiate Appendicitis from Ovarian Torsion
Both appendicitis and ovarian torsion can cause severe abdominal pain, but the location of the pain can help distinguish them. Appendicitis pain often begins near the belly button and shifts to the lower right abdomen, while ovarian torsion pain is usually localized to one side of the pelvis.
To confirm appendicitis, healthcare providers may order blood tests to check for infection and imaging studies such as a CT scan or ultrasound, which may reveal an inflamed appendix. Ovarian torsion is diagnosed through imaging that shows an enlarged ovary or disrupted blood flow. Both conditions require urgent treatment, so seek immediate medical attention if you suspect either.
Endometriosis
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, often on the ovaries, fallopian tubes, or pelvic lining. This condition can cause chronic pelvic pain, heavy periods, pain during intercourse, and infertility.
How to Differentiate Endometriosis from Ovarian Torsion
While both conditions can cause pelvic pain, endometriosis pain is often chronic and linked to menstrual cycles, whereas ovarian torsion causes sudden, severe pain. Endometriosis may also involve heavy menstrual bleeding, pain during intercourse, and infertility, which are not typical of ovarian torsion.
Diagnosis of endometriosis may involve imaging tests such as an ultrasound or MRI, but a definitive diagnosis often requires laparoscopy, a surgical procedure to visualize endometrial tissue. Ovarian torsion is diagnosed through imaging that shows an enlarged ovary or disrupted blood flow. If you experience chronic pelvic pain, consult a healthcare provider for evaluation and treatment options.
Ovarian Cyst
Ovarian cysts are fluid-filled sacs that develop on or inside the ovaries. While most cysts are harmless and asymptomatic, larger cysts can cause pelvic pain, bloating, or a sensation of pressure. In rare cases, complications such as rupture or torsion may occur.
How to Differentiate an Ovarian Cyst from Ovarian Torsion
Both ovarian cysts and ovarian torsion can cause pelvic pain, but cyst-related pain is often milder and intermittent, while torsion pain is sudden and severe. Large cysts may also cause bloating or a feeling of fullness, which is not typical of ovarian torsion.
Healthcare providers may use a pelvic ultrasound to differentiate between the two. A simple cyst appears as a fluid-filled sac, while ovarian torsion shows an enlarged ovary with reduced or absent blood flow. Persistent or severe pelvic pain warrants medical attention to determine the cause.
Fibroids
Fibroids are noncancerous growths that develop in or on the uterus. They can cause heavy periods, pelvic pain, frequent urination, and abdominal pressure. While usually not dangerous, fibroids can lead to complications such as anemia or fertility issues.
How to Differentiate Fibroids from Ovarian Torsion
Fibroids and ovarian torsion can both cause pelvic pain, but fibroid-related pain is often chronic and associated with heavy menstrual bleeding. Ovarian torsion, on the other hand, causes sudden, severe pain and is not linked to menstrual cycles.
Diagnosis of fibroids may involve a pelvic ultrasound or MRI to determine the size and location of the growths. Ovarian torsion is diagnosed through imaging that shows an enlarged ovary or disrupted blood flow. If you experience pelvic pain or abnormal bleeding, consult a healthcare provider for evaluation and treatment options.
Urinary Tract Infection (UTI)
A urinary tract infection (UTI) is an infection in any part of the urinary system, including the bladder, urethra, or kidneys. Common symptoms include burning during urination, frequent urination, pelvic pain, and cloudy or foul-smelling urine.
How to Differentiate a UTI from Ovarian Torsion
Both UTIs and ovarian torsion can cause pelvic pain, but UTIs often include symptoms such as burning during urination, frequent urination, or cloudy urine—symptoms not associated with ovarian torsion.
Healthcare providers may perform a urine test to check for bacteria or white blood cells to diagnose a UTI. Ovarian torsion is diagnosed through imaging that shows an enlarged ovary or disrupted blood flow. Seek medical care for appropriate treatment if you suspect a UTI or ovarian torsion.
Diverticulitis
Diverticulitis occurs when small pouches in the colon lining, called diverticula, become inflamed or infected. Symptoms include lower abdominal pain, fever, nausea, and changes in bowel habits, such as constipation or diarrhea.
How to Differentiate Diverticulitis from Ovarian Torsion
Both conditions can cause abdominal pain, but diverticulitis pain is often located in the lower left abdomen, while ovarian torsion pain is usually on one side of the pelvis. Diverticulitis may also involve fever and bowel changes, which are not typical of ovarian torsion.
Diagnosis of diverticulitis may involve a CT scan to detect inflamed or infected diverticula. Ovarian torsion is diagnosed through imaging that shows an enlarged ovary or disrupted blood flow. Severe abdominal pain warrants consultation with a healthcare provider for evaluation and treatment.
Mesenteric Ischemia
Mesenteric ischemia occurs when blood flow to the intestines is reduced, often due to a blood vessel blockage. Symptoms include severe abdominal pain, nausea, vomiting, and sometimes diarrhea or blood in the stool. This is a medical emergency requiring immediate treatment.
How to Differentiate Mesenteric Ischemia from Ovarian Torsion
Both conditions can cause sudden, severe abdominal pain, but mesenteric ischemia often includes nausea, vomiting, and blood in the stool—symptoms not typical of ovarian torsion.
Healthcare providers may use CT angiography to detect blood flow blockages for diagnosing mesenteric ischemia. Ovarian torsion is diagnosed through imaging that reveals an enlarged ovary or disrupted blood flow. If you suspect mesenteric ischemia or ovarian torsion, seek immediate medical care, as both are emergencies.
Treatment Options for Ovarian Torsion
Medications for Ovarian Torsion
Analgesics
Definition: Analgesics are medications used to relieve pain, ranging from over-the-counter options like acetaminophen to stronger prescription drugs.
How and When They’re Used: These medications are often the first choice for managing the intense abdominal or pelvic pain caused by ovarian torsion. After surgery, they play a key role in controlling discomfort during recovery.
Expected Outcomes: Pain relief is typically achieved within 30 minutes to an hour, depending on the type of analgesic, significantly improving patient comfort.
Antiemetics
Definition: Antiemetics are medications designed to alleviate nausea and vomiting, which are common symptoms of ovarian torsion.
How and When They’re Used: These are administered when nausea or vomiting occurs, often alongside other treatments. In hospital settings, they are typically given intravenously for faster relief.
Expected Outcomes: Relief from nausea and vomiting is usually achieved within 15–30 minutes, enhancing overall comfort and stability.
Antibiotics
Definition: Antibiotics are used to treat bacterial infections. While not directly used for ovarian torsion, they may be necessary if an infection arises as a complication.
How and When They’re Used: Prescribed when signs of infection, such as fever or an elevated white blood cell count, are present—often after surgery. They may be administered orally or intravenously, depending on the severity of the infection.
Expected Outcomes: Infections are generally controlled within 48–72 hours, reducing the risk of further complications.
NSAIDs
Definition: Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce inflammation and manage mild to moderate pain.
How and When They’re Used: Commonly prescribed after surgery, NSAIDs help alleviate pain and inflammation. They are typically used for short-term relief.
Expected Outcomes: Pain and inflammation usually subside within hours, supporting a smoother recovery process.
Opioids
Definition: Opioids, such as morphine, are powerful pain relievers used for severe pain that cannot be managed with other medications.
How and When They’re Used: Reserved for severe pain, opioids are often administered in hospital settings before or after surgery. Due to their potential for dependency, they are used for a limited duration under close supervision.
Expected Outcomes: Opioids provide rapid and effective pain relief, typically within 15–30 minutes, but require careful monitoring to minimize side effects.
Corticosteroids
Definition: Corticosteroids are anti-inflammatory medications that may reduce swelling and inflammation in specific conditions.
How and When They’re Used: Rarely used for ovarian torsion, corticosteroids might be considered in unique cases where inflammation contributes to symptoms. They can be administered orally or via injection.
Expected Outcomes: Inflammation reduction is typically observed within hours to days, depending on the dosage and method of administration.
IV Fluids
Definition: Intravenous (IV) fluids help maintain hydration and restore electrolyte balance, especially in patients experiencing severe vomiting or dehydration.
How and When They’re Used: Administered in hospital settings to stabilize patients before or after surgery, IV fluids are particularly beneficial for those unable to tolerate oral fluids.
Expected Outcomes: IV fluids quickly restore hydration and electrolyte levels, improving patient stability within hours.
Antispasmodics
Definition: Antispasmodics are medications that relieve muscle spasms, including those in the pelvic region.
How and When They’re Used: Used selectively to manage muscle spasms associated with ovarian torsion, these medications can be administered orally or intravenously.
Expected Outcomes: Relief from spasms is typically achieved within 30 minutes to an hour, enhancing patient comfort.
Hormonal Therapy
Definition: Hormonal therapy involves medications that regulate hormone levels, potentially reducing the risk of ovarian cysts that could lead to torsion.
How and When They’re Used: Often prescribed for patients with a history of recurrent ovarian cysts, hormonal therapy serves as a preventive measure rather than an acute treatment.
Expected Outcomes: Over time, hormonal therapy can decrease the frequency of ovarian cysts, lowering the risk of future torsion episodes.
Pain Management
Definition: Pain management encompasses a variety of strategies, including medications and physical therapies, aimed at alleviating pain.
How and When They’re Used: A comprehensive pain management plan is developed for patients with chronic pain following ovarian torsion or surgery. This may include medications, physical therapy, and counseling.
Expected Outcomes: Gradual improvement in pain levels is expected, leading to a better quality of life over weeks to months.
Procedures for Ovarian Torsion
Laparoscopy
Definition: Laparoscopy is a minimally invasive surgical procedure used to diagnose and treat ovarian torsion by untwisting the ovary.
How and When It’s Used: Often the first-line surgical treatment, laparoscopy involves a small incision and the use of a camera to guide the surgeon in restoring blood flow to the ovary.
Expected Outcomes: Most patients experience immediate symptom relief and recover fully within a few weeks.
Laparotomy
Definition: Laparotomy is an open surgical procedure used for more complex cases of ovarian torsion or when laparoscopy is not feasible.
How and When It’s Used: Reserved for severe cases involving significant ovarian damage or complications, this procedure requires a larger incision for better access.
Expected Outcomes: While recovery may take longer compared to laparoscopy, laparotomy effectively resolves torsion and prevents further complications.
Oophorectomy
Definition: Oophorectomy is the surgical removal of one or both ovaries, typically performed when the ovary is severely damaged and cannot be saved.
How and When It’s Used: Considered a last resort, this procedure is performed under general anesthesia when blood flow cannot be restored, or the ovary is necrotic.
Expected Outcomes: While the torsion is permanently resolved, patients may experience hormonal changes if both ovaries are removed, necessitating long-term hormonal therapy.
