[Pleural effusion and constrictive pericarditis secondary to bromocriptine treatment].

The case of a 60 year old patient with Parkinson's disease is reported, who, following 2 years of treatment with bromocriptine, presented a left pleural effusion in which chronic constrictive pericarditis was demonstrated. Studies aimed at establishing the etiology were negative. Upon withdrawal of bromocriptine, the pleural effusion disappeared and the patient remained asymptomatic, with only pleural thickening persisting in the thoracic radiography. The appearance of polyserositis as an undesirable effect of the use of bromocriptine is discussed. The first case associated to chronic pericarditis is reported.
