Figure 1 Esophageal and gastric submucosal hematomas. A: Initial endoscopic image showing esophageal strictures; B: Computed tomography (CT) scan showed a mixed high-density lesion in the small curvature of the gastric body (yellow arrow and circle); C: Submucosal hematoma occupying the esophageal lumen in the lower esophagus (yellow arrow); D: CT scan showed a vascular malformation with active bleeding in a branch of the left gastric artery (yellow arrow and circle); E: Angiography shows thickening and curvature of a branch of the left gastric artery with contrast spillage (yellow arrow and circle); F: Repeat CT scan showed that the hematoma was significantly smaller than before (yellow arrow and circle); G: Repeat endoscopy revealed esophageal hematoma rupture on the surface.
