Abstract

A 71-year-old man presented at the emergency department with an acute onset of hematochezia and abdominal pain that had developed 1 day previously. He had no history of surgery and was taking aspirin (100 mg) and clopidogrel (75 mg). CT revealed a short segmental concentric lower density bowel wall thickening at the proximal sigmoid colon. Sigmoidoscopy showed blue-colored elevated lesions and ruptured intramural hematomas with submucosal bleeding in the sigmoid colon. These findings correspond to intramural hematomas of the sigmoid colon. His symptoms were reduced with conservative treatment stopping aspirin and clopidogrel for 20 days. Here we report a case of non-traumatic intramural hematoma of the colon in a patient receiving dual antiplatelet agents. This had never been reported.
