Answer

Answer

Bacterial pneumonias have a predominantly focal segmental or lobar distribution, with or without pleural effusions. Atypical bacterial pathogens have variable radiographic findings, ranging from focal segmental to bilateral interstitial disease. P jiroveci (PJP) pneumonia typically manifests as bilateral patchy interstitial infiltrates. Of note, radiographic findings alone are not reliable for differentiating specific etiologies of CAP.
