Representative computed tomography (CT) scans performed within 1 month of death in a patient with combined pulmonary fibrosis and emphysema (CPFE) without lung cancer who died from pulmonary hypertension (A, B), and in another such patient with lung cancer who died from a non-respiratory cause (C). (A) Upper lobe showing centrilobular and paraseptal emphysema and bullae. (B) Lower lobe showing reticular opacities with peripheral and basal predominance and honeycombing, which was diagnosed as definite usual interstitial pneumonia (UIP) pattern. (C) Lower lobe showing thick-walled cystic lesions (TWCLs) larger than honeycombing with peripheral reticular opacities.
