摘　　要：目的：分析肺隔离症的影像所见，以便于早期诊断。材料和方法：１３例患者中，男性６例，女性７例，年龄６～６９岁，平均２５岁。最常见症状是咳嗽、咳痰，９例患者有反复或持续性肺部感染。１２例手术证实；１例未手术，结合影像所见及病史做出诊断。结果：胸像及ＣＴ主要表现为肿块或囊肿，８例ＣＴ中２例显示异常动脉供血，１２例为肺内隔离症，１例为肺外隔离症。结论：当患者有反复肺部感染病史，Ｘ线平片发现肺下叶后基底段囊状或肿块状阴影，经抗炎治疗长期不吸收，应怀疑本病。Ｂ超、ＣＴ或ＭＲＩ能显示其供血动脉，对诊断非常有帮助。Purpose: To analyse the imaging findings of pulmonary sequestration in order to make early diagnosis. Materials and Methods: Thirteen patients (6 men and 7 women) ranged in age from 6 to 69years (mean, 25 years). Cough and sputum were the most common symptoms. Repeated or persistent pulmonary infection occurred in 9 patients. Twelve seqestrations were proved surgically, one case not operated was diagnosed on the basis of imaging finding combined with appropriate history. Results: The main findings of plain films and CT were masses or cysts containing air and fluid. Abnormal arterial supply were shown in 2 of 8 cases with CT examinations. 12 sequestrations were intralobar, and 1 was extralobar. Conclusion: We considered that pulmonary sequestration should be suspected in patients with repeated pulmonary infection together with cysts or soft-tissue mass in the posterior basal segment of lower lobes shown by plain chest film and residual shadow failed to clear up after antibiotic treatment over a long period. US、CT and MRI are very helpful in establishing a definite diagnosis by showing the arterial supply.
