Abstract
A 73-year-old man with severe intellectual disability, malnutrition, and hypoalbuminemia presented to our hospital after experiencing vomiting following dinner. Electrocardiography revealed a sinus rhythm. Plain abdominal radiography showed branching radiolucency in the liver. Abdominal computed tomography (CT) revealed branching gaseous foci of low density in the portal vein and its tributaries, suggesting the presence of hepatic portal venous gas (HPVG). Abdominal contrast-enhanced CT showed a segmental lack of contrast enhancement in the intestinal wall despite the absence of vascular occlusion in the main trunk and branches of the mesenteric artery. The patient was diagnosed with non-occlusive mesenteric ischemia (NOMI) accompanied by HPVG. Peripheral parenteral nutrition, antibiotic treatment, and human serum albumin were administered. The HPVG disappeared approximately 20 h after hospitalization. Intravascular dehydration associated with hypoalbuminemia was considered to be the cause of NOMI; the latter improved through the early correction of dehydration and hypoalbuminemia. The presence of HPVG is usually considered a diagnostic clue in patients with abdominal catastrophe and is associated with high mortality. However, the current case demonstrates the pitfalls of assessing the severity of the underlying condition based solely on the presence of HPVG.
