Abstract
Parasitic leiomyoma is a type of myoma of the uterus that separates from the uterus and adheres to other abdominal organs. A case of parasitic leiomyoma that adhered to the small intestine and required partial resection of the ileum to achieve complete extraction of the tumor in a 51-year-old woman is reported. The patient was admitted to our hospital for lower abdominal pain. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) showed a tumor in the upper left of the uterus. A myoma of the uterus and a left ovarian tumor were suspected, and surgery was performed. During the operation, a soft, solid, brown-colored tumor was found. It adhered to the ileum and its mesentery and had no continuity with the uterus or the ovary. The tumor was removed with a part of the ileum. Postoperative histopathological examination revealed that the tumor was a parasitic leiomyoma.
