摘　　要：目的:探讨小儿先天性肺囊性腺瘤样畸形的CT表现以提高对该病的认识。方法:回顾性分析10例经过手术病理证实的先天性肺囊性腺瘤样畸形的CT表现,术前均行胸部CT平扫,4例做CT增强扫描,3例做MPR重建。结果:10例先天性肺囊性腺瘤样畸形的CT表现为单发大囊型2例,多发大囊型6例,多发小囊型2例;右肺受累4例,左肺受累6例;病变多累及单个肺叶,7例有不同程度的占位效应,病理检查为异常增生的管腔或腺瘤样结构。结论:CT检查是诊断先天性肺囊性腺瘤样畸形的可靠方法,根据CT表现可推测其病理分型,提高病变检出率,对临床治疗和判断预后起到积极的作用。Objective： To explore the CT manifestations of congenital cystic adenomatoid malformation （CCAM） in children in or- der to improve awareness of the disease. Methods： CT manifestations of CCAM in l0 children confirmed by surgery and pathological examination were analyzed retrospectively, chest CT scan was performed before surgery, 4 children underwent CT enhanced scan and 3 children underwent MPR reconstruction. Results ： CT manifestations of 10 children with CCAM included single large cystic type in 2 children, multi- ple large cystic type in 6 children and multiple small cystic type in 2 children. There were 4 children in right lung and 6 children in left lung, the lesions were mostly found in single pulmonary lobe. Seven children showed space occupying effect in varying degrees. Pathological exami- nation found paraplasmic glandular or bronchiolar structures. Conclusion： CT scan is a reliable method in diagnosing CCAM. Based on CT manifestations, the pathological type of CCAM might be predicted, the detection rate of CCAM can be improved, which plays an active role in clinical treatment and judging prognosis.
