Objective
To investigate the characteristics on chest high-resolution computed tomography (HRCT) of patients with interstitial pneumonia with positive myeloperoxidase antineutrophil cytoplasmic antibody (MPO-IP).
Methods
The extent of fibrosis and subtypes of emphysema on HRCT of MPO-IP patients were retrospectively analyzed and compared with idiopathic pulmonary fibrosis (IPF) cases admitted in the same period.
Results
From July 2014 to March 2016, 10 patients was diagnosed with IPF and 10 patients was diagnosed with MPO-IP. Emphysema was not different between two groups. Among the MPO-IP patients, 8 patients presented with a usual interstitial pneumonia (UIP) pattern. There existed statistical difference in the bronchial bifurcation level, the fibrosis score of lungs in the MPO-IP patients presented with UIP was lower than that in the IPF patients.
Conclusions
UIP is the predominant radiologic type of MPO-IP patients. Fibrosis in IPF is more serious than that in MPO-IP with UIP. Paraseptal and centrilobular emphysema are main forms in MPO-IP patients.
