Objective To study the imaging manifestation of congenital cystic adenomatoid malformation of the children's lung ( CCAM) in order to improve the recognition. Methods There are 7 case which were confirmed by operation and pathology as CCAM. X-rage chest films and CT scan were performed in all cases before operation, 3 of them were examined by high-resolution CT,1 of them was examined by enhancement CT . Results There are 4 cases in right lung,there are 3 cases in left lung. All lesion showed obvious space occupying sign . The pathologic findings, the cyst was paraplasmic glandular or bronchiolar structures. Conclusion X-ray examination and CT scan can help show some diagnostic signal for CCAM, CT scan can improve the detection rate of CCAM, and Imaging examination is a important method in diagnosing and treatmenting CCAM.%目的 探讨小儿先天性肺囊性腺瘤样畸形的影像学表现,以提高对该病的认识.方法 本文收集了7例经手术及病理证实的CCAM,术前行X线胸片及胸部CT平扫,3例病变区作高分辨率CT扫描,1例做增强扫描.结果 右肺受累4例,左肺受累3例,病变多累及单个肺叶,均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 X线胸片、CT检查对本病先期诊断有重要作用,CT检查能更好显示病变,提高病变检出率,对临床治疗和判断预后起到积极作用.
