Portal venous gas is caused by various pathological processes, both iatrogenic (complications of endoscopy) and non-iatrogenic (bowel ischemia, obstruction, perforated gastric ulcer, septicaemia). We report an immunocompromised patient suffering from metastatic cancer of the breast who developed severe gastroenteritis. Plain radiographs of the abdomen showed branching tubular lucencies that extended from the porta hepatis widely over the liver. A computed tomography performed to exclude air in the biliary tract demonstrated portal venous gas. Although the finding of portal venous gas has been associated with a high mortality rate and usually necessitates surgery, our patient survived without surgical intervention.

Portal venous gas is a worrying radiological sign that was described for the first time in 1955 among newborn children suffering from necrotizing enterocolitis. It was often related to mesenteric ischemia which mortality remains very high. Now, as radiological explorations increase, portal venous gas is more and more described in less pejorative contexts, such as hydrogen peroxide intoxication. It is what happened to our patient who underwent a hydrogen peroxide colic enema followed by a major and transient portal venous gas onset. This solved quickly and spontaneously.

Portal venous gas or hepatic portal venous gas (HPVG) found on imaging portends grave outcomes for patients suffering from ischemic bowel disease or mesenteric ischemia. HPVG is more rarely seen with severe but treatable abdominal infection as well as multiple benign conditions, and therefore must be aggressively evaluated. We report a 70-year old female who developed extensive intra- and extra-hepatic portal venous gas, pneumatosis intestinalis and free air associated with a perforation of the jejunojejunostomy after a gastrectomy for gastric carcinoma.

Portal venous gas is a radiographic finding with numerous causes. The most common etiologies include bowel ischemia or other intra-abdominal catastrophes. The finding of portal venous gas carries a high mortality rate. We report the first case of portal venous gas associated with anaphylactoid reaction to intravenous contrast dye in a middle-aged woman. This was likely secondary to anaphylactoid-induced ischemic colitis. This patient was managed conservatively and had a good outcome.
