Gallstone ileus is an uncommon and often life-threatening complication of cholelithiasis. In this case report, we discuss a difficult diagnostic case of gallstone ileus presenting as small gut obstruction with ischemia. A 56-year-old female presented with abdominal pain and vomiting. A CT scan was performed and showed an evolving bowel obstruction with features of gut ischemia with pneumobilia although no frank hyper density suggestive of a gallstone was noted. The patient underwent emergency surgery and a 60 mm obstructing calculus was removed from the patient's jejunum, with a formal tube cholecystostomy. JMS 2018: 21 (2):117-119
