Intramural hematoma of the gastrointestinal tract is an uncommon occurrence with the majority being localized to the esophagus or duodenum. Hematoma of the gastric wall is very rare, and has been reported most commonly in association with coagulopathy, trauma, hematologic disease, and therapeutic endoscopy. Here we describe a case of intramural gastric hematoma after epinephrine injection therapy for a gastric ulcer with underlying liver cirrhosis that was successfully managed with conservative therapy.
