Description:This anteroposterior (AP) chest x-ray revealed radiologic evidence of pulmonary pneumocystosis in the form of bilateral pulmonary interstitial infiltrates. This infection was due to the presence of an opportunistic fungal infection by the fungal organism Pneumocystis jirovecii, formerly known as Pneumocystis carinii.

Pneumocystis jirovecii is the causative agent of Pneumocystis pneumonia (PCP), one of the most frequent and severe opportunistic infections in immunocompromised patients. Pneumocystis organisms represent a large group of species of atypical fungi with universal distribution and pulmonary tropism, and each species has a strong specificity for a given mammalian host species.
