Abstract
A 74 year-old male had old pork curry for lunch and was referred to our hospital with a chief complaint of abdominal pain. There was tenderness in the upper abdomen with signs of peritonitis, and abdominal CT showed broad hepatic portal venous gas (HPVG) and low contrast in the small intestine. We diagnosed HPVG due to intestinal necrosis and an emergency operation was performed, however there was no intestinal necrosis but infectious enteritis was revealed. The pathological diagnosis was infectious enteritis of Clostridium perfringens from Gram staining and spore staining. HPVG sometimes occurs in the case of infectious enteritis so that we need to take infection into account when we encounter HPVG.
