Overview
Ovarian fibromas account for approximately 4% of all ovarian neoplasms and are the most common sex cord tumor. Fibromas are generally asymptomatic and typically detected in middle-aged women at palpation during routine gynecologic examination. They are associated with ascites in 40% of cases and with pleural effusions in a small percentage of cases. Meig syndrome consists of an ovarian fibroma with ascites and a pleural effusion.
Epidemiology
Fibromas are seen in 75% of patients with nevoid basal cell carcinoma syndrome.
Diagnosis
US
Fibromas most commonly manifest as solid, hypoechoic masses with sound attenuation; however, the US appearance is variable.
CT
Fibromas manifest as diffuse, slightly hypoattenuating masses with poor, very slow contrast enhancement.
MRI
Fibromas demonstrate homogeneous, relatively low signal intensity on T1-weighted MR images. On T2-weighted images, fibromas appear as well-circumscribed masses with low signal intensity containing scattered high-signal-intensity areas representing edema or cystic degeneration.
