纵隔肿瘤影像学特点的探讨(附58例分析)

目的　探讨纵隔肿瘤的影像学特点对定性诊断的价值。方法　结合经手术、病理证实的 5 8例纵隔肿瘤 ,回顾性分析其X线和CT影像学表现 ,再结合文献 ,提出对纵隔肿瘤定性诊断有价值的影像学特点。结果　前纵隔肿瘤 40例 ,包括胸内甲状腺 3 2例 (其中 5例为甲状腺癌 ,1例为甲状腺囊肿 ) ,胸腺瘤 3例 ,畸胎瘤 5例 (其中 1例穿破 ) ;后纵隔肿瘤 18例 ,均为神经原性肿瘤。结论　根据纵隔的分区和X线、CT影像学特点并结合临床 ,能正确做出纵隔肿瘤的定性诊断。

Mediastinal Tumors:Imaging Characters

Objective To study the value of imaging characters in diagnosing mediastinal tumors.Methods X-ray and CT findings of pathologically proved mediastinal tumors in 58 cases were analysed,the findings enabling qualitative diagnosis were recommended. Results There were 40 cases of anterior mediastinal tumors including intrathoracic thyroid tumors n=32,5 tyroid carcinomas and 1 thyroid cyst ,thymomas (n=3) and teratomas (n=5, 3 cases ruptured)]. All the other 18 cases in posterior mediastinum were neurogenic tumors.Conclusion Based on the combination of the mediastinal compartment knowledge, X-ray and CT findings of the tumors and the clinical information, the qualitative diagnosis of mediastinal tumors will be characterized correctly.
