Bilateral Fibrothecoma: A Rare Case in Young Woman

Fibrothecomas are rare sex cord stromal tumours. They usually occur in postmenopausal women and are mostly unilateral. They are usually associated with good prognosis; however, difficulties are encountered in establishing diagnosis. The treatment includes surgical resection. Here, the authors describe a rare case of a bilateral ovarian fibrothecoma in a 20-year-old female who presented with a large pelvic mass. On examination, there was a regular, immobile solid mass extending 30 weeks pregnancy size per abdomen. Pelvic examination revealed a firm nodular mass with minimal mobility and uterus could not be appreciated separately. On ultrasonography, a large solid mass arising from the pelvis superior and to the right of the uterus extending up to right hypochondrium was seen along with few cystic spaces and peripheral vascularity. Computerised tomography demonstrated two large solid cystic abdominopelvic mass lesion with internal solid enhancing areas and calcification of approximately 18 cm on the right side and 14 cm on the left side. The patient underwent exploratory laparotomy. Intra-operatively, the right ovarian mass was found, which was histopathologically confirmed as bilateral ovarian tumour (Bilateral Fibrothecoma).
