Ovarian fibromatosis associated with large pedunculated fibroma in a 30‐year‐old woman: A rare coincidence or variant?

Abstract

A 30‐year‐old nulligravida was referred under suspicion of large subserosal myoma. T2‐weighted magnetic resonance imaging revealed multilobulated solid mass in the left lower abdomen measuring 16 cm in longitudinal diameter. The ovarian surface was covered with a marked T2‐hypointense thick rim called “black garland sign,” forming multiple nodular masses ranging from 1 to 5 cm in diameter in some portions of the bilateral ovaries. By laparoscopic‐assisted minilaparotomy, the stalk of pedunculated mass originating from the left ovarian hilum was excised, followed by carrying out of the body after in‐bag morcellation using a surgical scalpel. Right ovarian exophytic nodular masses larger than 1 cm were excised using monopolar electrode needle. Pathological examination of excised right and left masses showed fibroblast‐like spindle cell proliferation with collagenous stroma; however, differences between right and left masses cannot be distinguished on a histological level. Postoperative diagnosis was ovarian fibromatosis coexisting with large pedunculated fibroma.
