Bezoar as a cause of portal vein pneumatosis: a case report
Abstract
Pneumatosis of the portal vein is considered a rare imaging sign rather than a disease. It usually occurs in patients with digestive tract diseases such as intestinal obstructive diseases, mesenteric vascular diseases, closed abdominal trauma, and liver transplantation. Because of its high mortality rate, it is also termed the “sign of death.” Hawthorn contains tannic acid, and seafood is rich in calcium, iron, carbon, iodine, and other minerals and proteins. Thus, consuming both hawthorn and seafood together can result in the formation of an indigestible complex in the body, acting as the main pathogenic factor in patients with intestinal obstruction. We herein describe a patient with duodenal obstruction caused by hawthorn who developed the hepatic portal venous gas sign and was cured by nonsurgical treatment.
