Lung lesions occurred in 17 (80.9%) patients with NCP, while normal lungs occurred in 4 (19.1%) patients. Among the 17 patients with pulmonary lesions, 14 (82.4%) cases showed multiple lesions in both lungs ( Fig.2A) . Besides,10 patients had lesions distributed in the peripheral zone (subpleural)( Fig.2A) , and 7 cases showed both peripheral zone and medium-to internal zone were all involved.15 (88.2%) cases showed simultaneous involvement of multiple pulmonary lobes (≥2) (Fig.2B) , among them 12 cases (70.6%) with more than 4 lobes were involved.6 patients (85.7%) in serve group displayed 4-5 lobes were involved simultaneously, which was significantly higher than that in the mild group (60% ). However,there was no difference in lesion location and whether bilateral lung involvement between these two group. Table 2 shows the manifestations of various major chest CT features in 17 patients with NCP. GGO, Vascular enlargement and Cobblestone/Reticular pattern were the three major feature of the disease (Fig.3) , with an incidence of 100%, 76.5% and 70.6%, respectively and followed by Consolidation and Mixed pattern, accounting for 52.9%.In addition, mediastinal lymphadenopathy and hydrothorax had the lowest incidence of 17.6% and 5.9%, respectively.
