BWH emergency radiology—surgical correlation: small-bowel GI stromal tumor perforation

We present the radiological and intraoperative correlation of a large necrotic gastrointestinal stromal tumor (GIST) with features of a tumor-bowel fistula and perforation in a 49-year-old woman presenting to the emergency department with a 4-day history of worsening abdominal pain, vomiting, and diarrhea. The patient underwent urgent exploratory laparotomy for partial resection of the small bowel, with primary anastomosis. The purpose of this article is to emphasize the importance for emergency radiologists to be familiar with this entity and its possible complications to help guide the surgeons in the patient’s management.
