Case Report
A 53-year-old white man was admitted to the Brooklyn (NY) Veterans Administration Hospital because of fever and productive cough of two weeks' duration. Eight years prior to this admission, a chest roentgenogram was said to have shown bullous emphysema of both upper lobes.
Except for a temperature of 38°C (100.4°F), absent breath sounds over both upper lung fields, and impaired percussion noted over the right upper portion of the chest anteriorly, the findings from physical examination were unremarkable.
A roentgenogram of the chest (Fig 1) revealed evidence of giant bullous disease of both upper lobes along with free fluid in the bulla occupying the right upper lobe. In addition, an infiltrate was noted around the base of the fluid-filled cavity. A 5-tuberculin unit skin test gave 20 mm of induration. A Gram stain of a sputum smear showed mixed organisms; acid-fast bacilli stains times three were negative. The results of a complete blood count and serum chemistry studies were unremarkable.
