Gastritis and colitis in two patients who each presented with epigastric and abdominal pain and received positive test results for COVID-19 in the emergency department. Coronal contrast-enhanced CT images of the abdomen and pelvis show thickening of the gastric wall and associated mucosal hyperenhancement (arrows in a) and thickening of the ascending and descending colon with mucosal enhancement (arrows in b), findings that are indicative of gastritis (a) and colitis (b), respectively. Note the hepatic steatosis in a.
