title: Pneumatosis cystoides coli.
abstract: Pneumatosis cystoides coli in most cases is a disease of unknown etiology. In a few patients, it is secondary to an infarction or ulcerative colitis. Associated pulmonary emphysema is not uncommon. The gas pockets, whcih may be of varying size, can be identified along the contour of the bowel. The left side of the colon is more frequently involved than the right. The lesion is usually segmental. The rectum is almost always spared. Symptoms are negligible and operation is not required.
