[Meigs' syndrome associated with adenocarcinoma of the left fallopian tube]

A 52-year-old woman was admitted to the hospital with dyspnea on exertion and a feeling of abdominal fullness. Chest radiographs revealed a moderate bilateral pleural effusion. Examination of the effusion was in conclusive. Thoracoscopy and thoracic computed tomography (CT) failed to provide evidence pertaining to the etiology of the recurrent effusion. Elevation of serum CA-125 levels suggested the presence of an intrapelvic tumor, which was substantiated by pelvic CT. Laparotomy revealed a small amount of ascites. The resected specimen revealed a tumor of the left fallopian tube, which was histologically to be poorly differentiated adenocarcinoma. The pleural effusion disappeared after removal of the tumor and Meigs' syndrome was subsequently diagnosed. Primary fallopian tube adenocarcinoma is a rare cause of Meigs' syndrome.
