Gastric Ischemia and Cecal Necrosis: A Simultaneous Presentation of Two Rare Entities.

A 65-year-old woman presented with right lower quadrant (RLQ) abdominal pain of three days duration. During her hospitalization, she underwent computed tomography (CT) of the abdomen, duplex ultrasound of the abdomen, esophagogastroduodenoscopy (EGD), and colonoscopy as part of a diagnostic workup. The workup identified high-grade obstructions of the celiac artery (CA), superior mesenteric artery (SMA), atypical appearing gastric ulcers, and a diffusely ulcerated cecum, which created a mass-like appearance. The patient developed cecal perforation despite mesenteric vessel stenting and ultimately required right hemicolectomy for definitive management. This case report represents a rare presentation of simultaneous gastric ischemia and cecal ischemia with necrosis in a patient with underlying peripheral vascular disease.
