A "mass-forming" variant of ischemic colitis following COVID infection: a case report and review.

Abstract

Ischemic bowel disease is a common disease of bleeding in the lower digestive tract. There are many risk factors for ischemic bowel disease. Abdominal pain, bloody stool and diarrhea were often the triad of clinical manifestations. The endoscopic appearance included colonic mucosal edema and erosion; submucosal hemorrhage, mucosal necrosis, mucosal shedding, ulcer formation et al. But in rare cases its manifestations are highly variable, which makes clinical diagnosis challenging. Colonoscopy and pathology are the keys to diagnosis. We present a case of "mass-forming" variant of ischemic colitis following COVID infection.
