Ovarian fibroma


Ovarian fibroma is a benign stromal/sex cord tumor and the commonest in this category. Middle age females are more commonly affected. The tumor size can be large at presentation as in this case. Many associations are known with this tumor, e.g. Meigs and Gorlin-Goltz syndromes. On ultrasound, it appears hypoechoic with acoustic shadowing, even in the absence of calcifications. On MRI, it has a low T2 signal which is considered a characteristic feature of fibrous origin tumors. On imaging, it can resemble a large pedunculated subserosal uterine leiomyoma.
