Value of digital fluoroscopy for the diagnosis of Pneumatosis coli

Two cases are presented of benign pneumatosis coli diagnosed on digital flu oroscopic barium enema examinations, in which the gas-filled cysts in the c olonic wall were only recognized by postprocessing of the images (i.e. incr easing the brightness and contrast settings) at the computer workstation. W hen digital barium enemas are performed, we therefore recommend image postp rocessing to evaluate polypoid lesions in order to differentiate pneumatosi s coli from true colonic neoplasms.
