[Pneumatosis cystoides intestinalis of the splenic flexure].

We describe a case of pneumatosis cystoides intestinalis with unusual localization and radiologic features. Barium enema showed multiple, rounded, submucosal masses, which were polypoid and airless and were localized to a 20 cm segment of the splenic flexure. There was no extraluminal gas on X-ray. Puncture of these formations via colonoscopic biopsy did not result in deflation of air. Surgical resection was performed and the classical features of pneumatosis cystoides intestinalis were found. Isolated splenic flexure involvement in conjunction with atherosclerotic cardiovascular disease may suggest that pneumatosis cystoides intestinalis is a reparative process after ischemic injury.
