We present the results of computed tomography (CT) scan of gastric schwannoma in a 50-year-old woman who was admitted with non-specific abdominal pain. Her Upper GI series showed a large submucosal mass along the greater curvature at the gastric body. Dynamic biphasic CT scan showed that the mass was a well-defined homogeneous soft tissue mass that exhibited no contrast enhancement in the arterial phase but slightly inhomogeneous enhancement in the venous phase. Although schwannoma is extremely rare in this location, it should be considered in the differential diagnosis of gastric submucosal tumors.
