Various Bronchiolar Lesions Accompanied by Idiopathic Pleuroparenchymal Fibroelastosis with a Usual Interstitial Pneumonia Pattern Demonstrating Acute Exacerbation

A 63-year-old man presented with persistent cough and progressive dyspnea. Computed tomography showed irregular pleural thickening and fibrotic changes with volume loss in the upper lobes, and subtle reticulation in the lower lobes. Pleuroparenchymal fibroelastosis (PPFE) was diagnosed based on the...

Sumario:A 63-year-old man presented with persistent cough and progressive dyspnea. Computed tomography showed irregular pleural thickening and fibrotic changes with volume loss in the upper lobes, and subtle reticulation in the lower lobes. Pleuroparenchymal fibroelastosis (PPFE) was diagnosed based on the findings of a surgical lung biopsy. Bronchiolar lesions, including proliferative bronchiolitis, constrictive bronchiolitis obliterans, and peribronchiolar metaplasia were evident on pathology. A usual interstitial pneumonia (UIP) pattern was also observed in the lower lobes. Three weeks after the biopsy, an acute exacerbation occurred. We herein describe a rare case of idiopathic PPFE with various bronchiolar lesions and a UIP pattern in which an acute exacerbation developed.
