Historically, the presence of portal venous gas (PVG) on plain abdominal films was an indication for exploratory laparotomy and seen as an ominous finding with a mortality of almost 100%. Over the last decades, the introduction of CT scan has facilitated the diagnosis of PVG with a subsequent decrease in the mortality. PVG has been associated with ischemic bowel but also with other more benign conditions. We describe a case of a young patient with PVG of uncertain etiology with delayed portal vein thrombosis, with a discussion on the different conditions associated with PVG and the approach to the patient with PVG.
