[Dyspnea at rest].

A 54 year old woman complained about progressive dyspnea. She was markedly obese and presented with right-sided pleural effusion of undetermined origin. Treatment for congestive heart failure did not reduce the pleural effusion. Pleural or pulmonic tumor was not found, a large intraabdominal mass contained ovarian tumor-cells. The exudative pleural fluid was interpreted as Meigs'-syndrome in view of the coexisting ascites.
