Background In idiopathic pulmonary fibrosis (IPF) the distribution and spatial-temporal progression of fibrotic changes may be influenced by general or locoregional conditions. From this perspective, patients with asymmetrical disease (AIPF) may be unique. Methods This retrospective study included 32 patients (26 men, mean6SD age 6967 years) with AIPF, as defined by an asymmetry ratio (most affected e least affected fibrosis score)/(most affected + least affected fibrosis score)>0.2. The global fibrosis score was the average of the right and left scores. Patients with AIPF were compared with 64 matched controls with symmetrical IPF. Results Patients with AIPF did not differ from controls i
