title: Computed tomography colonographic findings of pneumatosis cystoides coli.
abstract: Pneumatosis cystoides coli (PCC) is an uncommon condition in which multiple gas-filled cysts in the walls of the colon. Patients with PCC initially complain of various symptoms including abdominal discomfort, constipation, diarrhea, hematochezia, vomiting, and fever. We recently diagnosed PCC by computed tomography (CT) colonography in 2 patients. Two patients visited the outpatient clinic presenting with hematochezia, diarrhea, or abdominal pain. No underlying cause of PCC was found. Colonoscopy revealed multiple submucosal nodules covered with normal mucosa in the colon. However, CT colonography showed multiple gas-filled cysts within the walls of colon.
