纵隔肿瘤的CT诊断

CT diagnosis of mediastinal tumors

目的探讨CT对纵隔肿瘤的诊断价值,以提高对纵隔肿瘤的准确诊断。方法收集16例经手术或病理证实的纵隔肿瘤的相关资料,结合文献,进行回顾分析。结果胸腺瘤6例,胸内甲状腺3例,支气管囊肿2例,恶性淋巴瘤2例,神经源性肿瘤2例,畸胎瘤1例。CT定位准确率100%,定性准确率93.75%。结论CT检查是诊断纵隔肿瘤最有效的方法之一,根据纵隔肿瘤的发生部位、影像学特征及得当的检查方法,并密切结合临床资料及实验室检查,一般均能对纵隔肿瘤做出准确的诊断。

Objective To explore the value of CT for diagnosing the mediastinal tumors, in order to improve the accuracy of the diagnosis on mediastinal tumor. Methods 16 cases of mediastinal tumors proved by surgery or pathology were analyzed retrospectively. Results There were 6 cases of thymoma, 3 of intrathoracic thyroid, 2 of bronchial cyst, 2 of malignant lymphoma, 2 of neurogenic tumor, and 1 of teratoma. The accuracy rate of CT localization and CT diagnosis were 100% and 93.75% respectively. Conclusion CT examination is one of the most effective ways in diagnosing mediastinal tumor. According to the mediastinal tumor location, imaging features with proper examining method, closely combing the clinical data and lab examination, generally, mediastinal tumors can be diagnosed accurately.
