Several mechanisms have been suggested for the development of hypoxemia in cirrhosis. A few patients of portal hypertension due to non cirrhotic liver disease with cyanosis have also been reported earlier. We report probably the first documented case

Various criteria are used together for the scintigraphic diagnosis of cirrhosis as no single criterion may be reliable. However, low right-to-left hepatic lobe uptake ratio has been reported to be sensitive and specific for alcoholic cirrhosis. A low
