目的总结分析肺隔离症的影像学诊断。方法对肺隔离症进行X线平片、CT检查及主动脉造影。结果X线平片示4例呈卵圆形、不规则长方形、密度均匀的密实阴影,CT片示2例呈类圆形密实影,本组6例患者经主动脉造影证实为肺隔离症。结论肺隔离症在X线上无特殊诊断意义。如多次肺炎发作或没有症状患者肺下叶后基底段有囊性或块状阴影,在诊断中应该考虑到有肺隔离症的可能,必要时行主动脉造影进行证实。
Objective To summarize the imaging diagnosis of pulmonary sequestration. Methods Pulmonary sequestration was examined by X-ray, CT and aortography. Results X-ray showed 4 cases of oval, irregular rectangle, dense density of dense shadow, CT showed 2 cases were round and round like shadow, the group of 6 patients confirmed by aortic angiography pulmonary sequestration. Conclusion Pulmonary sequestration has no special diagnostic significance on X-ray. Such as multiple episodes of pneumonia or no symptoms in patients with posterior lobe of the basal segment of cystic or massive shadow in the diagnosis should be considered the possibility of pulmonary sequestration, if necessary, confirmed by aortic angiography.
