Rapid reversal of colonic pneumatosis with restoration of mesenteric arterial supply

Pneumatosis cystoides intestinalis (PCI) is characterized by gas-filled cystic lesions within the wall of the large intestine and presents along a spectrum of clinical severity ranging from benign to life threatening. Etiopathogenesis is multifactorial and postulated to result from either mechanical or bacterial causes. In this report, we present a patient with chronic abdominal pain evaluated with colonoscopy revealing segmental PCI isolated to the distal colon. Further investigation revealed an abdominal aortic aneurysm (AAA) compromising the inferior mesenteric artery takeoff. Endovascular repair of the AAA resulted in clinical resolution of abdominal pain and endoscopic resolution of PCI. To our knowledge, this is the first report to document endoscopic resolution of PCI with restoration of mesenteric arterial supply, highlighting vascular insufficiency as a predisposing and reversible pathogenic mechanism.
