Areas of consolidation ( n\u2009=\u200914), areas of GGO ( n\u2009=\u200913), linear opacities ( n\u2009=\u200911), lymphadenopathy ( n\u2009=\u20095), and pleural effusion ( n\u2009=\u20098) were uncommon. The parenchymal abnormalities were peripherally located in 47 (65.2%) of the cases. Cavitations within nodules\/masses were more frequently present in immunocompromised patients than in immunocompetent patients ( P\u2009=\u20090.009), and in AIDS patients than in non-AIDS immunocompromised patients ( P\u2009=\u20090.002). Air bronchograms within nodules\/masses were more frequent present in immunocompetent patients than in immunocompromised patients ( P\u2009=\u20090.005).
