目前,对纵隔肿瘤的临床定性诊断还是一个比较困难的问题。临床与病理学诊断的符合率约为51.7～76.6%。为了提高临床诊断的准确性,国内外开展了纵隔充气造影、同位素扫描、血管造影以及纵隔镜和经皮纵隔穿刺细胞学检查等方法。本文根据我院1957年7月至1980年9月经手术和病理证实的原发性纵隔肿瘤及囊肿共94例的资料,进行临床分析,试图找寻对良、恶性原发性纵隔肿瘤的诊断线索。 At present, the qualitative diagnosis of mediastinal tumor is still a difficult problem. The coincidence rate of clinical and pathological diagnosis is about 51.7 to 76.6%. In order to improve the accuracy of clinical diagnosis, mediastinum inflatable imaging, isotope scanning, angiography, and mediastinal and transcutaneous mediastinal cytology were performed at home and abroad. According to the data of 94 cases of primary mediastinal tumors and cysts confirmed by surgery and pathology in our hospital from July 1957 to September 1980, we conducted a clinical analysis to try to find the diagnostic clues for benign and malignant primary mediastinal tumors.
