经胸超声诊断纵隔淋巴瘤的临床价值分析

Clinical value of transthoracic ultrasonography in diagnosis of mediastinal lymphoma

目的探讨经胸超声检查在纵隔淋巴瘤诊断中的应用价值。方法回顾性分析经病理确诊的55例纵隔淋巴瘤患者的声像图特征,观察肿块位置、内部回声及周围淋巴结情况,分析超声对纵隔淋巴瘤的诊断效能。结果 55例纵隔淋巴瘤患者声像图特征均表现为前上纵隔实性包块,47例包块内部可见结节状低回声和/或网状稍强回声,43例肿块周围或全身其他部位可见淋巴结肿大。超声诊断纵隔淋巴瘤的敏感性为85.45%,特异性为83.72%,约登指数为0.79;不同医师间诊断一致率为80.61%,Kappa值为0.612。结论纵隔淋巴瘤超声表现具有一定特征性,经胸超声可作为诊断纵隔淋巴瘤的重要手段。

Objective To explore the application value of transthoracic ultrasonography in the diagnosis of mediastinal lymphoma.Methods The ultrasonographic features of patients with mediastinal lymphoma confirmed by pathology were analyzed retrospectively.The location of lesions,the characteristics of internal echo and the peripheral lymph nodes were observed.The accuracy of ultrasound imaging in diagnosis of mediastinal lymphoma was statistically analyzed.Results The sonographic features of 55 cases of mediastinal lymphoma were solid mass of anterior superior mediastinum,47 cases showed mass with internal hypoechoic nodules and/or reticular stronger echo,43 cases had enlarged lymph nodes around mass or other parts of the body.The sensitivity of ultrasound in diagnosis of mediastinal lymphoma was 85.45%,the specificity was 83.72% and the Youden index was0.79.The consistent rate from different operators was 80.61% and the Kappa value was 0.612.Conclusion The ultrasonic manifestations of mediastinal lymphoma has certain characteristics,and transthoracic echocardiography can be used as an important means in the diagnosis of mediastinal lymphoma.
