A pitfall in triple contrast CT of penetrating trauma of the flank

This brief report describes the case of a 20-year-old man who was stabbed in the left flank. He underwent triple contrast helical CT of the abdomen and pelvis that showed a hyperdense focus in the area of the stab wound. This structure was a chip fracture of pelvis, but was misinterpreted as contrast extravasation, and the patient underwent negative exploratory laparotomy.
