We report a case of fatal pulmonary toxoplasmosis, which clinically resembled Pneumocystis carinii pneumonia (PCP). Conventional diagnostic methods for toxoplasmosis lack sensitivity. Bronchoscopy and histological evaluation of transbronchial biopsy specimens failed to identify the infecting organism. At autopsy there was evidence of disseminated infection.
