3.5 Imaging characteristics of PB in children.
All the 269 enrolled patients underwent chest CT scan and 262 (97.4%) showed pulmonary consolidation, 125 (46.5%) had segmental or lobar atelectasis, 127 (47.9%) with pleural effusion and170 (63.2%) with pleural thickening. The incidence of pulmonary consolidation and pleural effusion were higher in multiple group (100% vs 95.1%, 56.8% vs 38.9%, respectively, P<0.05). However, there was no difference in the incidence of segmental or lobar atelectasis and pleural thickening between the two groups. ( Table 4)
