Images of a CPFE patient without lung cancer who died from right heart failure owing to deterioration of pulmonary hypertension. (A) CT scan performed 6 months prior to death; view of the right lower lobe showing TWCLs and traction bronchiectasis with reticulation on the pleural predominance. (B) CT scan performed within 1 month of death showing enlargement of TWCLs and simultaneous progression of reticulation despite smoking cessation. (C) Gross photo of the right lower lobe showing TWCLs (square). (D) Paramount view showing TWCLs apposed to honeycombing in the right lower lobe; corresponds to the CT scan (Figure 4-B) and gross photo (Figure 4-C). (E) High-power view of the square lesion in Figure 4-D showing fibroblastic focus (arrow) in the fibrous walls of the TWCLs.
