[Hydrothorax as a major symptom of decompensated liver cirrhosis]

A case of a 54-year patient with decompensated liver cirrhosis is presented. As a major symptom rapidly increasing hydrothorax on the right side without marked ascites was observed. Diagnosing and simultaneously establishing etiology of hydrothorax on the base of clinical and laboratory findings was a difficult process. Imaging tests did not show any signs of splenomegaly.
