title: Colonic spasm: a possible mechanism for thumbprinting.
abstract: A patient with "colonic thumbprinting" on a contrast examination of the colon, typical of ischemic colitis both clinically and radiographically, is presented. Both surgical and pathologic evaluations were performed within hours of the contrast enema and revealed no relevant abnormality. Colonic spasm is a possible mechanism for this finding.
