Pneumocystis Jiroveci Pneumonia

摘要

We present a case of Pneumocystis jiroveci (formerly P. carinii) Pneumonia (PJP). A 60 year old HIV+ male with a CD4+ count of 144 cells/mm3 complaining of cough, dyspnea, and chest pain was ultimately diagnosed with PJP by lung biopsy after negative bronchoalveolar lavage (BAL). This case demonstrates typical radiographic findings of PJP, with symmetric bilateral lower lobe reticulonodular ground-glass opacities, complicated by spontaneous pneumomediastinum and pneumothorax.
