| 目的 分析儿童支原体肺炎64层CT薄层重建及高分辨率CT(HRCT)的表现特点。方法 回顾性分析117例儿童支原体肺炎患者的64层CT薄层重建及HRCT资料,分析该病的CT特征。结果 117例患儿中,93例(79.49%) CT表现为实变,其中节段性大叶实变影76例(64.96%),伴支气管充气征34例,肺节段性部分性不张18例;小叶性实变17例(14.53%);肺门或纵隔淋巴结肿大37例,胸腔积液36例;气胸3例;纵隔气肿2例。小气道改变包括树芽征59例,小叶中心结节影54例;磨玻璃影15例,细支气管扩张26例,马赛克灌注征11例。结论 儿童支原体肺炎主要CT表现为树芽征或小叶中心结节,可与大片实变并存。64层CT薄层重建及HRCT对支原体肺炎的诊断有重要价值。 |

| Objective To observe the thin reconstruction of 64-slice CT and HRCT features of mycoplasma pneumoniae pneumonia (MPP) in children. Methods The data of the thin reconstruction of 64-slice CT and HRCT in 117 children with MPP were analyzed retrospectively, and CT features of them were observed. Results Consolidation was observed in 93 (79.49%) cases, lobar or segmental consolidation in 76 cases (64.96%), which with bronchial inflatable sign in 34 and with mild volume decrease of the involved lobe in 18 cases. Lobular consolidation was observed in 17 cases (14.53%). Lymphadenectasis were found in 37 and pleural effusion was seen in 36 cases, while pneumothorax and mediastinal emphysema were detected in 3 and 2 cases, respectively. Small airway changes were also observed: Tree in bud was observed in 59 cases, centrilobular nodules in 54, ground-glass shadow in 15, small bronchiectasis in 26 and mosaic perfusion syndrome in 11 cases. Conclusion The main appearances of children with MPP are the tree-in-bud pattern or centrilobular nodules, which can coexist with consolidation. Thin reconstruction of 64-slice CT and HRCT have novel value in diagnosis of MPP in children. |
