Methods CT features of DPB in 13 patients were retrospectively analyzed. Results Among the 13 cases ，the distribution of lesions was bilateral with diffuse in 12 cases and local in 1 case. The chest CT apperances of DPB were as follows ：1diffuse small nodules accompanied by tree-in-bud sign in 13 cases ；2small airway bron-Chiectasis in 12 cases, mucoid impaction in 3 cases; 3inflamma-tory patchy consolidation in 8 cases, small cavity in 2 cases, interstitiell fibrosis in 3 cases; 4 Chronic paranasal sinusitis was found by CT examination in 11 cases, mostly involving the maxillary sinus; the changes of CT features before and after treatment; the lesions were absorptive in different degree after treatment 1-3 months later. Conclusion MSCT features of DPB are characteristic, playing an important role in the diagnosis of DPB.
