[Hepatopulmonary syndrome]

Hepatopulmonary Syndrome is an uncommon clinical situation of unknown cause. It remains the focus of intense investigation and ongoing debate. The authors present a case of a 77 year old man with chronic liver disease known for 5 years, who developed central cyanoses, digital clubbing and hypoxemia. On searching for the cause of these clinical features, the diagnosis of Hepatopulmonary Syndrome was admitted and confirmed by contrast enhanced echocardiography using agitated saline, and also by technetium 99m-labelled macroaggregated albumin scanning.
