Rectal Teratoma coexistent with an Ovarian Teratoma: A Case Report

ABSTRACT

We report a case of rectal teratoma coexistent with an ovarian teratoma. To our knowledge, this is the first radiologic report of rectal teratoma. Computed tomography (CT) showed a sharply demarcated cystic and fatty mass with amorphous calcification in the rectum. A double-contrast barium study showed a well-defined intraluminal rectal mass without mucosal destruction. Imaging findings of rectal teratoma allow for correct preoperative diagnosis. CT was helpful in differentiating rectal teratoma from other rectal lesions.
