Conclusion
Ovarian fibromas are unilateral in about 90% of cases and are rarely malignant. Ovarian fibromas most frequently occur in middle-aged women, with an average age of 48 years.[2,4] In this report, all cases were unilateral and occurred after the age of 48 years. In the three cases presented here, all patients complained of a distended abdomen and the presence of a hard, palpable lump. Similar to other pelvic masses, no specific symptoms led to a precise diagnosis in these three cases of ovarian fibroma.
On CT, Ovarian fibromas usually appear as a homogenous solid tumour with delayed contrast enhancement.[2] However, cystic changes may occur in fibromas such as those observed in Case 3, in which an ovarian fibroma displayed cystic degeneration. All patients showed delayed contrast enhancement after contrast administration. In this report, ascites and pleural effusion are present in all patients, supporting the condition known as Meigs Syndrome.
Ovarian fibromas are typically rare. Due to the rarity of these tumours, they could easily be misdiagnosed as other types of ovarian carcinoma. Therefore, increased awareness and knowledge of the characteristics of fibroma on CT imaging, including solidity of the mass, unilaterality, pattern of contrast enhancement, ascites, and pleural effusion are important for establishing an accurate diagnosis.
