Autopsy findings in the intestine and stomach. (A) Markedly dilated and necrotic small intestine that spilled out as the abdomen was opened, suggesting an increased intestinal and intra-abdominal pressure. (B) Numerous bubble-like aerocysts are diffusely present in the intestinal mucosa. (C–F) Histologically, aerocysts are identified particularly in the lamina propria mucosae and submucosa of the small intestine (C–E) and stomach walls (F). Hematoxylin and eosin staining. Bar = 1.5 mm for C, and 200 μm for D, E, and F.
