title: Ovarian tumor complicated by a colo-ovarian fistula.
abstract: Although a fistula is a rare complication of ovarian tumor, we encountered four patients with cole-ovarian fistulas in three years. The first case was demonstrated by following barium enema by the extravasation of barium from the sigmoid colon, and by a gas-containing lesion in the tumor observed on computed tomography. Mature cystic teratoma was the pathological diagnosis in two cases. A mixed germ cell tumor and a serous cystadenoma of low malignant potential were diagnosed in the other two cases. The etiology and differential diagnosis of cole-ovarian fistula are reviewed.
