Pneumatosis intestinalis (PI) is the radiographic finding of air in the intestinal wall. It occurs in about 0.37% of patients who undergo radiographic imaging and is becoming a more common finding in critically ill patients. With the more frequent use of computed tomographic scanning, PI is increasingly reported. The spectrum of conditions that cause PI ranges from benign to life threatening. Intensivists need to distinguish between the conditions for which emergent surgical intervention is required and those in which the presence of PI is less clinically worrisome.
