【摘要】目的探讨纵隔三分区法在占位性病变诊断中的使用价值。方法对103例手术病理证实的纵隔占位性病变影像学表现进行分析，应用三分区法，了解各种病变在各分区的分布情况。结果按发病率排列：前上为淋巴类病变、胸腺肿瘤、畸胎类肿瘤、胸内甲状腺肿等；前下为心包肿瘤、畸胎类肿瘤等；后纵隔为淋巴类病变、食管肿瘤、神经源性肿瘤、动脉瘤等。结论此方法简便实用，定位准确，利于定性诊断。

    【Abstract】ObjectiveTo investigate three compartments of mediastinal anatomy in the diagnosis of space- occupying kesions.MethodsX- ray and CT images of 103 mediastinal lesions confirmed by surgery or/and pathology retrospectively studied.The CT manifestation of all cases were all analysed.ResultsUsing mediastinal three- compartments protocol and according to the occupying lesions,anterio- superior mediastinal lesions were lymphadenovarix,thymoma,teratoblastoma and intrathyroma,etc.In anterio- inferior mediastinum,heat tumors,fatty tumor,teratoblastoma were found successively.There were lymphadenovarix,esophageal tumors,neurogenic tumors,aneurysms and so on.ConclusionThe results suggested that this protocol was more terse and practical than others in the diagnosis of space- occupying lesions. ......
