Right hemidiaphragm elevation in a patient with idiopathic pulmonary fibrosis and dyspnea. Posteroanterior (a) and lateral (b) radiographs show pulmonary fibrosis with low lung volume and elevation of the right hemidiaphragm, concerning for paralysis. Axial (c) and coronal (d) CT images demonstrate diaphragm crura (arrows) without thinning, arguing against paralysis. CT images with lung window views in the axial (e) and coronal (f) plane show more lung fibrosis on the right than on the left. Right hemidiaphragm elevation likely reflects the greater degree of fibrosis and volume loss on the right.
