Pneumocystis carinii meningoradiculitis in a patient with AIDS.

Pneumocystis carinii is a common opportunistic pathogen in patients infected with the human immunodeficiency virus (HIV). Pneumocystis carinii pneumonia is common, while extrapulmonary infections with Pneumocystis carinii have been reported sparingly. The clinical features are frequently nonspecific. The detection of Pneumocystis carinii in cerebrospinal fluid (CSF) has not been reported thus far. In this report, an unusual case of Pneumocystis carinii meningoradiculitis in an HIV-infected patient who had previously received primary prophylaxis with trimethoprim-sulfamethoxazole is presented.
