Perigastric Hematoma Masquerading as a Gastric Tumor.

Perigastric and intramural gastric hematomas rarely occur, with most cases associated with trauma, coagulopathy, and peptic ulcer disease. Furthermore, hematomas in the upper gastrointestinal tract are commonly located in the esophagus and duodenum. In this case report, we describe a hematoma masquerading as a gastric tumor on esophagogastroduodenoscopy (EGD) in a 54-year-old male presenting with melena. Initial computed tomography (CT) imaging suggested gastrointestinal stromal tumor (GIST) as the probable cause. We performed endoscopic ultrasound (EUS) with findings consistent with a perigastric hematoma, which aligned with the patient's diagnosis of splenic vein thrombosis (SVT) and numerous collateral vessels communicating with the hematoma. Interventional radiology (IR) was consulted for further management, although we ultimately chose a conservative approach.
