Core Tip
Core Tip: Pleuroparenchymal fibroelastosis (PPFE) has been classified among rare idiopathic interstitial pneumonia and is characterized by predominantly upper lobe involvement. However, there is increasing evidence for the coexistence of other interstitial lung diseases in the same lobe. Herein, we report a very rare case of PPFE with laterality, unilateral PPFE. The diagnosis of PPFE should be made after multidisciplinary discussion. In cases of unilateral upper lobe predominant fibrosis, physicians should consider the diagnosis of PPFE and identify the progression of PPFE after diagnosis.
