Bilateral ovarian teratoma presenting with a clinical picture of acute abdomen

We describe the case of a 30-year-old patient with bilateral mature cystic teratoma (MCT) of the ovaries. The patient had been complaining of mild abdominal pain for several months that had suddenly become severe. Early diagnosis at the emergency room was acute appendicitis, but definitive diagnosis was bilateral ovarian teratoma. We therefore recommend considering ovarian teratomas in the differential diagnosis of acute abdomen in young women in an emergency care setting.
