Cavitary lung lesions caused by Pneumocystis jirovecii in setting of common variable immune deficiency

Abstract

Pneumocystis pneumonia affects immunocompromised hosts. The typical imaging finding is bilateral diffuse ground glass opacities. Here we presented a case of Pneumocystis causing biopsy-confirmed cavitary lung lesions in a patient with a predominant B cell defect with common variable immune deficiency.
