Pleural effusion due to hepatic cirrhosis and ascites is well known, but hepatic hydrothorax in the absence of ascites is a rare complication. We report a case of liver cirrhosis due to hepatitis C virus with a large and recurring pleural effusion that had an apparent abdominal source in the absence of ascites. We review the characteristics and treatment for hepatic hydrothorax in the absence of ascites.Hepatic hydrothorax is defined as the presence of significant pleural effusion in a cirrhotic patient without primary pulmonary or cardiac disease (1). Pleural effusions, as a whole, are rarely associated with liver cirrhosis with or without ascites. The incidence of hydrothorax due to liver cirrhosis was shown to be 2% (2), but was reported to be 0 . k 12.2% in decompensated cirrhosis (1,3-6). Hepatic hydrothorax in the absence of ascites (HHAA) is a rare complication in decompensated liver cirrhosis (7, 8) and its pathogenesis is still unknown. We report a case of HHAA and provide a review of all previously published reports.
Case reportA 41-year-old man was admitted to our hospital, with dyspnea and cough. He had a past history of a traffic accident, which necessitated a blood transfusion at the age of 16. He was known to be positive for anti-hepatitis C virus antibody. Breath sounds were decreased and dullness on percussion over the lower three-fourths of the right hemithorax was noted. The liver edge was not palpable below the right costal margin. He showed no sign of ascites on physical examination.
