Ovarian thecoma with massive pleural effusion in postmenopausal women: A case report.

Previous clinical reports of benign ovarian thecoma, associated with hydrothorax, are rare. The present study presents the case of a 58-year-old women exhibiting right massive pleural effusions and elevated cancer antigen (CA)125, and a pelvic ultrasound revealed a hypoechoic mass. An exploratory laparotomy was subsequently performed. During the surgery, the left ovary measured 20×15×15 cm and had a smooth surface with no excrescences or papillary projections. The patient underwent right salpingo-oophorectomy. Pathological diagnosis was determined as benign ovarian thecoma. The chest radiograph revealed no pleural effusion 6 days following the surgery. The present case demonstrated a benign ovarian thecoma, associated with massive hydrothorax and elevated CA125, which mimicked an ovarian malignancy.
