title: [Three cases of multiple infarcted regenerative nodules in liver cirrhosis after gastrointestinal hemorrhage].
abstract: An infarction of regenerative nodules in liver cirrhosis is a rare abnormality characterized by their coagulative necrosis. We presume that ischemic necrosis is induced by a sudden reduction in the portal and arterial blood flows after blood loss or shock. Most patients with infarcted regenerative nodules have experienced previous episodes of gastrointestinal hemorrhage. Awareness of the entity of infarcted regenerative nodules and its inclusion in the differential diagnosis of multiple hepatic nodules in liver cirrhosis is important, particularly in patients with an episode of gastrointestinal bleeding. The possible difficulty of differentiating infarcted regenerative nodules in liver cirrhosis from hypovascular hepatocellular carcinoma by initial imaging findings alone means that a liver biopsy and serial imaging might be helpful in the differential diagnosis. We report three cases of multiple infarcted regenerative nodules in liver cirrhosis after gastrointestinal hemorrhage.
