儿童先天性肺气道畸形的CT表现与病理对照分析

目的 探讨儿童先天性肺气道畸形（CPAM）的CT征象及其与病理改变的关系。方法 回顾性分析经手术病理证实的142例CPAM的临床及CT资料，采用Stocker 5型分法对142例CPAM进行病理分型，观察其CT特征，并与病理结果对照。结果 本组142例CPAM患者中，Stocker 1型52例（52/142，36.62%），CT表现为肺内多发大小不等含气囊肿；2型68例（68/142，47.89%），CT表现为肺内多发含气小囊肿；3型1例（1/142，0.70%），CT表现为右肺大片实变，其内见少许充气支气管影及含气小空腔；4型21例（21/142，14.79%），CT表现为肺外周多发分隔的巨大囊腔；未见0型病例。结论 CT可有效提示CPAM的病理类型。

CT features of congenital pulmonary airway malformation in children and its pathology comparative analysis

Objective To investigate CT features of congenital pulmonary airway malformation (CPAM) in children, and to explore their relationship with pathology. Methods Clinical manifestations and CT features of 142 CPAM children confirmed by pathology were retrospectively analyzed. The children were classified to 5 pathological types according to Stocker''s type. CT features were analyzed and compared with pathological results. Results Fifty-two cases (52/142, 36.62%) were classified as Stocker type 1 CPAM, and CT showed multiple unequal air cysts in lung fields, while 68 cases (68/142, 47.89%) were classified as Stocker type 2 CPAM, CT showed multiple small air cysts in lung fields. One case (1/142, 0.70%) was classified as Stocker type 3 CPAM, CT showed large consolidation in right lung and inflatable bronchi shadows and small cava containing air were noticed. Meanwhile, 21 cases (21/142, 14.79%) were classified as Stocker type 4 CPAM, CT showed giant cysts with multiple septa on the periphery of the lung. No Stocker type 0 case was identified. Conclusion CT can effectively indicate the pathological type of CPAM.
