Portomesenteric venous gas in a 2-week-old Holstein calf.

A 2-week-old Holstein Friesian female calf was presented with profuse diarrhea and abdominal distension. Clinicopathological findings included marked hypoproteinemia, hypoglycemia and leucopenia, mild hyperlactatemia, and hyperfibrinogenemia. On abdominal ultrasonography, features were consistent with portomesenteric venous gas (PVG), a rare condition reported in the medical literature. The PVG in this calf was associated with severe gastrointestinal illness and sepsis.
