Tumors of the appendix are rare diseases and sometimes mimic a hydrosalpinx. Because, in females, the appendix is proximal to the uterus and an ovary, appendix disorders can be difficult to distinguish from hydrosalpinx, paraovarian cysts, and ovarian tumors by diagnostic imaging. We report on a 54 year-old post-menopausal female who presented with a growing cystic pelvic mass. The mass was in fact a low-grade appendiceal mucinous neoplasm that was misdiagnosed pre-operatively as a hydrosalpinx. Transvaginal ultrasonography and magnetic resonance imaging revealed an 88-mm cystic mass in the right adnexal region. CT findings did not indicate continuity between the tumor and the intestinal tract. Laparoscopic surgery was performed. Intraoperative observation revealed that the mass originated from the ileocecal valve, and she was diagnosed with an appendix tumor. The tumor was resected by a surgeon during laparoscopic assisted surgery. Laparoscopic surgery can be useful for differential diagnosis and treatment of adnexal and appendiceal tumors.
