A 63-year-old woman was admitted to our hospital with fever and feces mixed with blood and pus. Colonoscopy revealed a slight elevated lesion covered with normal mucosa, and the drained pus at the center of the lesion in the rectosigmoid colon. Abdominal ultrasonography, computed tomography and MRI showed a cystic and heterogeneous lesion, suggesting a pelvic abscess. The patient was diagnosed as having an intrapelvic abscess draining itself spontaneously. Surgery was performed, and the operative findings showed swelling of the right ovary and adhesions among the appendix, uterus and rectum. The microscopic findings showed a right ovarian abscess and phlegmonous appendicitis, suggesting that the abscess had been formed by inflammation of the appendix affecting the right ovary. A rare case of spontaneous drainage of an ovarian abscess into the rectum is reported.
