Gastric intramural hematoma, “intramural dissection” or “false aneurysm”, is a rare and dangerous condition which may be more broadly classified as a spectrum of acute gastric mucosal injury. It is postulated that disruption of the mucosa and blood vessels within the submucosal layer results in dissection of the muscularis propria from the mucosa, with eventual clot formation. While a majority of cases resolve with conservative management, we describe a successfully managed case requiring surgical intervention. Progression of the haematoma was documented both endoscopically and surgically in an elderly anticoagulated patient who suffered a complication of therapeutic endoscopic intervention. A review of the literature is presented.
