Bowel ischemia and perforation as a complication of COVID-19 in a 65-year-old man with a history of asthma, hypertension, and hyperlipidemia. (a–c) Axial (a, c) and coronal (b, d) intravenous contrast material–enhanced CT images of the abdomen and pelvis show significant pneumatosis of the cecum and right ascending colon (dashed arrows in a and d), with associated perforation of the ascending colon (AC and dashed arrows in b) and a large complex fluid collection with an enhancing rim, indicative of an abscess (solid arrows in b). The abscess is filled with extravasated fecal material. Note the mesenteric venous gas (solid arrows in a), associated with pneumatosis. Note also the small amount of ascites and mesenteric congestion (* in a and d). Portal venous gas is present (solid arrows in c and d). Peripheral airspace disease (black arrow in d) in the right lower lobe is also depicted.
