Abstract

Ischemic necrosis of the cirrhotic liver is rare because the liver has dual blood supply and an extensive collateral system. However, it may occur in the condition of sudden reduction of hepatic arterial flow such as acute blood loss or shock Recently, we experienced two cases of ischemic necrosis of the liver assoicated with cirrhosis. Those were presented as space-occupying lesions on the radiological study. In contrast with hepatocellular carcinoma, these lesions showed neither hypervascularity nor deposition of injected lipiodol. Repeated percutaneous fine needle cytology revealed no evidence of malignant cells, Furthermore, short-term follow-up examination showed decrease in size and/or extent of the lesions, It is important to differentiate these lesions from tumorous condition because interventional trial such as transarterial chemoembolization may further aggravate the ischemic lesion and unnecessary surgery r impression of hepatocellular carcinoma in cirrhotic patients should be avoided,
