Pleural effusion: a rare manifestation of acute pulmonary blastomycosis.

A 47-year-old woman presented with cough, pleuritic chest pain and fever of three weeks duration. Although the patient lived in an area where blastomycosis is endemic, this diagnosis was not initially considered owing to the presence of consolidation and a large pleural effusion on the initial chest roentgenogram. Cultures of sputa, bronchial washings and pleural fluid documented the presence of pleuropulmonary infection with Blastomyces dermatitidis. Therapy with amphotericin B was associated with rapid clinical, roentgenographic and bacteriologic resolution of both pleural and parenchymal lung disease.
