Viridans streptococcal pulmonary parenchymal infections
M. R. Pratter and R. S. Irwin
Pulmonary parenchymal infections were caused by viridans streptococci in
two patients. Pleural empyema and lung abscess occurred in a previously
healthy adult; an uncomplicated pneumonia developed in an immunocompromised
host. In the first case, the diagnosis was ascertained by percutaneous lung
abscess aspiration, transtracheal aspiration, and thoracentesis culture
findings. In the second case, the diagnosis was established by
transtracheal aspiration culture results.
