GGO were present in all patients(100%) in both groups, and Cobblestone/Reticular pattern occurred in mild and sever group were 60% and 85.7%, respectively, without significant different. The consolidation, Mixed pattern and Vascular enlargement features were up to 100% in the severe group, significantly higher than 20%, 20% and 60% in the mild group. Consolidation and Mixed pattern had significant differences between the two groups (p =0.002). In addition, the incidence of Air-bronchogram, Dilated bronchi with thickened wall and Fibrosis in the severe group was significantly higher than that in the mild group (10%). Nodule/Thorn pear signs were found 50% in mild cases, significantly higher than those in severe cases (p<0.01). Mediastinal lymphadenopathy and hydrothorax were rare,but both occurred in severe cases. Fig.4 and Fig.5 showed the CT features of mild case and serve case underwent NCP.
