Coronal section image of chest computed tomography (CT) of a patient with PPFE (a). The ratio of the length of the lung apex to the hilum (a) and the length of the apex to the base (b) of the right lung was measured using axial section images on chest CT. Representative chest radiographs of rightward tracheal deviation (arrows) in a PPFE patient (b) and an IPF patient with the evolution of disease (c)
