[Intestinal pneumatosis and portomesenteric gas: a case review].

Intestinal pneumatosis (presence of gas in the intestinal wall and in the portomeseteric veins) is an infrequent clinical situation that has been associated with extended bowel necrosis and fatal outcome. However, there are other reasons that can justify these findings without such an outcome. Recent advances in diagnostic imaging techniques, especially multislice computerized tomography (MSCT), have allowed precise and quick diagnosis of these entities.
