Ovarian Fibroma: Signs, Causes, And How To Treat

Ovarian fibroma is a non-cancerous tumor that develops in the ovary. These growths are made up of fibrous tissue and are typically harmless. The exact cause of ovarian fibromas is not well understood, but they are thought to arise from the cells that make up the ovary. These tumors are usually discovered incidentally during imaging tests for other reasons. 

While ovarian fibromas are usually benign, they can sometimes grow large enough to cause symptoms or complications. It is essential to consult a healthcare provider for proper evaluation and management if you suspect you may have an ovarian fibroma.

What Are the Symptoms of Ovarian Fibroma

Some women experience menstrual irregularities, frequent urination, or constipation.  Rarely, they can lead to weight gain or a feeling of fullness in the abdomen.  If you notice these symptoms, consult your healthcare provider for proper evaluation and management.

  • Pelvic pain: Ovarian fibromas can cause dull or sharp pain in the lower abdomen or pelvis that may worsen during menstruation or intercourse.
  • Abdominal bloating: Patients may experience a feeling of fullness or swelling in the abdomen, which can be persistent and unrelated to eating or bowel movements.
  • Irregular menstrual cycles: Some individuals with ovarian fibromas may notice changes in their menstrual periods, such as heavier or lighter flow, irregular timing, or missed periods.
  • Frequent urination: Fibromas pressing on the bladder can lead to increased urgency to urinate, even when the bladder is not full.

Causes of Ovarian Fibroma

While the exact cause is unknown, hormonal factors and genetic mutations may play a role in their development.  Ovarian fibromas are most commonly seen in women of reproductive age and can be associated with certain syndromes such as Gorlin syndrome and basal cell nevus syndrome.

  • Ovarian fibromas can develop due to genetic factors, with certain individuals having a higher predisposition to this condition based on their family history.
  • Hormonal imbalances, such as an excess of estrogen, can contribute to the formation of ovarian fibromas in some women.
  • Endometriosis, a condition where tissue similar to the lining of the uterus grows outside the uterus, may lead to the development of ovarian fibromas.
  • Ovarian fibromas can be associated with Meigs syndrome, a rare condition characterized by the presence of a benign ovarian tumor, ascites (fluid in the abdomen), and pleural effusion (fluid around the lungs).
  • In some cases, previous abdominal

Types Of Ovarian Fibroma

Ovarian fibromas are categorized into three main types: cellular fibroma, mitotically active cellular fibroma, and fibrosarcoma. Cellular fibromas are the most common and typically benign. Mitotically active cellular fibromas have increased cell division activity but are still usually non-cancerous. Fibrosarcomas are rare and malignant, requiring more aggressive treatment. Identifying the specific type of ovarian fibroma is crucial for determining appropriate management.

  • Cellular ovarian fibroma is a rare subtype characterized by increased cellularity and a higher risk of recurrence compared to typical fibromas.
  • Fibrosarcoma of the ovary is an aggressive type of ovarian fibroma with malignant potential, necessitating prompt diagnosis and treatment.
  • Juvenile granulosa cell tumor with fibroma is a unique ovarian tumor that combines features of both juvenile granulosa cell tumors and fibromas, typically affecting young women.
  • Sclerosing ovarian fibroma is a variant characterized by dense fibrous tissue and hyalinization, often leading to diagnostic challenges due to its atypical presentation.

Risk Factors

Risk factors for ovarian fibroma may include hormonal imbalances, such as elevated levels of estrogen, and certain genetic conditions like basal cell nevus syndrome. Women who are of reproductive age or have a history of endometriosis may also be at increased risk. Regular gynecological check-ups and monitoring can help in early detection and management of ovarian fibromas.

  • Age is a significant risk factor for ovarian fibroma, with most cases being diagnosed in women between the ages of 30 and 50 years old.
  • Hormonal factors play a role in the development of ovarian fibroma, as estrogen levels can impact the growth of fibroid tumors within the ovary.
  • Obesity has been identified as a risk factor for ovarian fibroma, with studies showing a higher prevalence of fibroids in women with higher body mass index (BMI).
  • Family history of ovarian fibroma or other reproductive conditions can increase the likelihood of developing this tumor, suggesting a genetic predisposition.
  • Certain medical conditions, such as polycystic ovary syndrome (PCOS) or endometriosis,

Diagnosis of Ovarian Fibroma

A biopsy may also be done to analyze tissue samples.  Your doctor will review the results to determine if the tumor is benign or malignant.  Early detection is key for effective treatment and management of ovarian fibroma.

  • Imaging studies such as ultrasound and MRI can help identify the presence of ovarian fibroma by visualizing the characteristic features of the tumor.
  • Blood tests may be conducted to measure levels of certain hormones or tumor markers that can be associated with ovarian fibroma.
  • A pelvic exam performed by a healthcare provider can sometimes detect an ovarian fibroma by feeling for abnormal masses in the pelvic area.
  • A biopsy, where a small sample of tissue is taken from the suspected fibroma for examination under a microscope, can provide a definitive diagnosis.
  • Laparoscopy, a minimally invasive surgical procedure, may be recommended to directly visualize and biopsy the ovarian fibroma for accurate diagnosis.

Treatment for Ovarian Fibroma

Treatment options for ovarian fibroma may include surgery to remove the tumor, especially if it is causing symptoms or is suspected to be cancerous. In some cases, doctors may recommend close monitoring without immediate intervention. Medications may also be prescribed to manage symptoms such as pain. It is important to discuss with your healthcare provider to determine the most suitable treatment plan for your specific situation.

  • Surgery is often the primary treatment for ovarian fibromas, with the removal of the tumor and affected ovary through a procedure known as an ovarian cystectomy or oophorectomy.
  • In cases where the fibroma is small and asymptomatic, a "watchful waiting" approach may be recommended, with close monitoring of the tumor's size and symptoms over time.
  • Hormonal therapy, such as oral contraceptives or gonadotropin-releasing hormone agonists, may be used to help shrink the fibroma or alleviate associated symptoms like pain or abnormal bleeding.
  • If the fibroma is causing significant pain or discomfort, over-the-counter pain medications or prescription pain relief may be prescribed to manage symptoms.

Frequently Asked Questions

What early signs should I look for with ovarian fibroma?

Early signs of ovarian fibroma may include pelvic pain, bloating, urinary symptoms, and abdominal swelling. Consult a healthcare provider for diagnosis.

What precautions should be taken for ovarian fibroma?

Regular monitoring with ultrasound, discussing symptoms with a healthcare provider, and considering surgical removal if causing symptoms or complications.

Are there any risks associated with untreated ovarian fibroma?

Yes, untreated ovarian fibromas can grow larger and cause pain or pressure symptoms. In rare cases, they may lead to complications such as torsion or rupture.

How is ovarian fibroma typically managed?

Ovarian fibromas are usually managed through surgical removal of the tumor, especially if it's causing symptoms or there's concern for malignancy.

Is ovarian fibroma likely to come back after treatment?

Ovarian fibromas rarely recur after surgical removal. Regular monitoring is advisable to detect any possible recurrence early.
