Pneumatosis Intestinalis in the Adult: Benign to Life-Threatening Causes

¹ All authors: Department of Radiology, Duke University Medical Center, Box 3808 DUMC, Durham, NC 27710.

OBJECTIVE. The frequency of detection of pneumatosis intestinalis (PI) appears to be increasing. This increase may be the result of increased CT use. New medications and surgical procedures have been reported to be associated with an increase in the incidence of PI. The purpose of this review is to provide an update on the imaging features and clinical conditions associated with PI.

CONCLUSION. This article illustrates the imaging findings of PI due to benign and life-threatening causes, with emphasis placed on describing newly associated conditions and also the imaging appearance on CT.
