Fig. 1From: Clinical significance of radiological pleuroparenchymal fibroelastosis pattern in interstitial lung disease patients registered for lung transplantation: a retrospective cohort studyRadiological pleuroparenchymal fibroelastosis (PPFE) pattern on high-resolution computed tomography. a. Definite PPFE pattern. A 57-year-old male with idiopathic PPFE had definite PPFE. He received unilateral cadaveric lung transplantation after waiting for 266Â days. Pathological PPFE was confirmed in the explanted lung. b. Consistent PPFE pattern. A 55-year-old male with IPF.
