超声对纵隔肿瘤的诊断价值

Diagnostic Value of Ultrasonography in Mediastinal Tumors

目的 评价常规超声及介入超声对纵隔肿瘤的诊断价值。方法 对临床诊断前纵隔肿瘤的 5 6例患者进行超声检查 ,并对其中 46例进行超声引导下穿刺活检。结果 5 6例前纵隔肿块超声均能显示 ,显示率 10 0 % ;纵隔肿瘤穿刺活检者获确切病理诊断的占 73 .0 % ( 3 2 / 44) ,可疑诊断及不能帮助诊断者各占 13 .5 % ( 6/ 44)。无并发症发生。结论 常规灰阶超声能对大多数前纵隔肿瘤作出定位诊断 ;实时超声观察能清楚地显示肿块与心脏大血管的关系 ,从而准确地引导穿刺活检 ,使超声引导下纵隔肿瘤的穿刺活检成为一项安全可靠、简便、价廉的技术。

Objective To assess the diagnostic value of ultrasonography (US) and interventional US in mediastinal tumors. Methods Fifty six patients who were clinically diagnosed anterior mediastinal tumors were examined with US and 46 tumors were performed biopsy with 18G or 16G needle under US guidance. Results All 56 anterior mediastinal tumors were detected by US with a detection rate of 100%. A definite pathologic diagnosis was made in 32 of 44 cases (73.0%). The pathologic diagnosis was inconclusive and not achieved in 6 patients (13.5%), respectively. No complications of biopsy were found. Conclusion Real time US could clearly show the relationship between the tumor and the heart or vessels, and enable accurate tissue sampling. US guided percutaneous biopsy is a valuable method in the diagnosis of mediastinal tumors because it is easy to perform, safe, reliable and relatively cheap. [
