Imaging Reveals Bowel Abnormalities in Patients with COVID-19

Caption

Non-contrast axial (A) and coronal (B) CT performed in a 54-year-old man demonstrates pneumatosis cystoides intestinalis (arrows) in a long segment of ileum. Adjacent mesenteric congestion is also noted (thin arrow). Laparotomy demonstrated no frank bowel necrosis. Low power photomicrograph (H and E, 40x) of the ileum (C) shows ischemic degenerative changes of the mucosa with villous blunting (left) and withered crypts. There is marked submucosal edema with large empty spaces consistent with pneumatosis (*). High power view (H and E, 400x) (D) of the superficial submucosa shows arterioles with fibrin thrombi (arrowheads) beneath the damaged mucosa.
