肺隔离症35例临床病理分析

Pulmonary sequestration-A clinico-pathologcal Analysis of 35 cases

分析经手术病理证实的肺隔离症35例，男女之比3：2，中位年龄35岁，本前仅6例诊断正确，其余多误诊为肺囊肿、肺癌或良性肿瘤。本组35例中，叶内型30例，叶外型5例，位于左下叶24例，右下叶11例。胸部X线表现为边缘清楚的实性、囊性肿块和浸润性阴影，胸部CT及MRI对显示异常动脉有重要价值，而主动脉造影对本病确诊有决定性意义。

35 cases of pulmonary sequestration, identified by surgicea-pathologically,were analysed. Only 6 cases were correctly diagnosed before operation, the other 29 cases were misdignosed as cyst, lung cancer or benign tumor. In 35 cases with 30 cases of intralobular type and 5 cases of extra lobular type, the lesion were found in the left lower lobe (24), right lower lobe (11 ). The manifestation of Chest X-ray were well defined mass-like density, cystic shadow, or infiltration shadow, Imaging with CT scan and MRI has important vaIue in establishing a definite diagnosis by showing the anomalous artery. However, retrograde aortodraphy plays a decisive role for confirming the diagnosis.
