Abstract

Diagnosis of gastrointestinal stromal tumors (GISTs) of the terminal part of the small intestine on ultrasound examination can be difficult because of their similarity in appearance to gynecological tumors. We present a case of a 49-year-old asymptomatic female patient with GIST of the small intestine, which presented as a pelvic mass, mimicking an ovarian tumor. Tumor was diagnosed during the control check up and ultrasound gynecological examination. Computed tomography (CT) showed tumor mass in the pelvis on the right and free fluid in the lesser pelvis. During the surgery, exploration of the abdominal cavity displayed tumor of the terminal part of the small intestine (ileum). The uterus and both adnexes were normal. The patient was treated by resection of the terminal part of the small intestine and termino-terminal anastomosis. Immunohistochemical evaluation demonstrated positive vimentin, positive CD117, and negative CD 34. In the presence of a pelvic mass, especially if other unusual anamnestic data are present, the possibility of other than a gynecologic tumor has to be considered.
