title: Pneumocystis carinii pneumonia presenting as an upper lobe cavity after aerosolized pentamidine prophylaxis in an HIV-infected patient.
abstract: We describe an atypical diagnostic feature of a breakthrough Pneumocystis carinii pneumonia (PCP) during primary prophylaxis with aerosolized pentamidine. Our case disclosed infiltrates restricted to the left upper lobe. After 2 weeks a solitary cavity developed. Diagnosis was easily established by bronchoalveolar lavage when performed in the affected segment bronchus. Cavitation clearly demonstrated localized infection, with tissue destruction as one main pathogenetic pattern of a breakthrough PCP during aerosolized pentamidine prophylaxis.
