Aim: To describe a rare variant of ovarian fibroma.Background: Ovarian fibroma is a rare entity, but is the most common solid ovarian tumor. Most of these tumors are solid, and most commonly mistaken with uterine fibroid. In rare cases, they may show a mix of solid-cystic components.Case description: In this case report, we present a rare case of bilateral ovarian fibroma with extensive cystic degeneration, appearing as predominantly cystic adnexal mass on ultrasound.
Conclusion:A rare condition with extensive degeneration may be impossible to distinguish with the ovarian epithelial tumor. Thus, ultrasound finding of a cystic lesion should not be used to exclude an ovarian fibroma.
