多层螺旋CT对纵隔肿瘤的诊断评价

Diagnostic evaluation of MSCT in the diagnosis of mediastinal tumors

目的探讨多层螺旋CT对纵隔肿瘤的诊断价值。方法分析68例经穿刺活检或手术病理证实的纵隔肿瘤MSCT表现特点,重点观察肿瘤的部位、大小、形态、密度及其与周围组织结构的关系。结果68例纵隔肿瘤中,前纵隔肿瘤51例,其中胸腺瘤32例,生殖细胞肿瘤15例,淋巴瘤4例;中纵隔肿瘤10例,包括淋巴瘤9例,胸腺瘤1例;后纵隔肿瘤7例,均为神经源性肿瘤;其中CT定位准确率100%(68/68),定性准确率93%(63/68)。结论 MSCT对纵隔肿瘤具有较高的诊断价值。

Objective To assess the value of MSCT in the diagnosis of mediastinal tumors. Methods The manifestations of MSCT were retrospectively analyzed in 68 cases of mediastinal tumors. The location, size, morphology, density and relation with the surrounding structures of the tumors were observed. Results In 68 cases of mediastinal tumors, there were 51 cases of anterior mediastinal tumors including thymoma （n =32）, germinoma （n =15） and lymphadenoma （n =4）. There were 10 cases of medium mediastinum tumors including lymphadenoma （n = 9） and thymoma （n =1）. All the other 7 cases in posterior mediastinum were neurogenic tumors. The accuracy rate of CT localization and CT diagnosis were 100% （68/68） and 93% （63/68） respectively. Conclusion MSCT has high value in the diagnosis of mediastinal tumors.
