Introduction
Liver cirrhosis is a common disease with many known complications. Cirrhosis represents a clinical spectrum, ranging from asymptomatic liver disease to hepatic decompensation. Manifestations of hepatic decompensation include variceal bleeding, ascites, hepatic encephalopathy, hepatorenal syndrome, hepatopulmonary syndrome, portopulmonary hypertension and hepatocellular carcinoma. There are reports about infarcted regenerative nodules in cirrhotic livers after gastrointestinal hemorrhage.
Case presentation
We report three Caucasian patients (one female and two male patients; ages: 52, 54 and 60 years) with decompensated liver cirrhosis, who showed newly infarcted regenerative nodules at necropsy. Two of them suffered from gastric variceal bleeding. Histopathology showed extensive infarction in all three cases.
Hemorrhage and inflammatory changes were also observed around the infarcted regenerative nodules.
Conclusion
These patients showed focal liver lesions, to be considered in the differential diagnosis of cirrhotic livers. Infarcted regenerative nodules may be underdiagnosed in patients with decompensation of cirrhosis. In order to differentiate these lesions from malignant tumors, serial imaging seems to be helpful. However, the main differential diagnosis should be an abscess. It is important to know the wide spectrum of image appearances of these lesions. Hypotension can lead to a reduction of portal and arterial liver flow. Since variceal bleeding or septic shock can induce hypotension - as observed in our patients - we conclude that this leads to infarction of such nodules.
