Abstract

Appendiceal mucocele is a rare entity that can present in a variety of ways. The incidence is estimated to be 0.2% to 0.3% of appendectomy specimens. Appendiceal mucocele refers to dilatation of the appendiceal lumen by an abnormal accumulation of mucus. It can be confused radiologically with an ovarian teratoma, which may prove to be a diagnostic challenge. Early diagnosis and prompt treatment is important to avoid unintended rupture and the development of pseudomyxoma peritonei. The diagnosis of mucocele of the appendix as well as other appendiceal neoplasms should be considered by the gynecologist in the differential diagnosis of a right-sided adnexal tumor. We report a case of appendiceal mucocele mistaken for ovarian teratoma in a 59-year-old women.
