肺癌肝转移瘤的超声诊断分析

Study on hepatic metastasis from lung cancer with ultrasonography

目的 评价超声对肺癌肝转移瘤的诊断价值,进一步提高超声诊断的准确率。方法 回顾200例肺癌肝转移瘤的超声图像并进行分析。结果 200例肝转移瘤中多发病变119例,占59.5％;单发81例,占40.5％。右叶多于左叶,转移瘤大小0.5～9.7cm不等,多数呈圆形或类圆形。高回声型53例,占26.5％;低回声型98例,占49.0％;中等回声及混合回声型分别为32例和17例,占16％和8.5％。结论 肺癌肝转移瘤的超声图像表现呈多样形态,但只要掌握其特点,紧密结合临床大多可明确诊断。

Objective To evaluate the value of ultrasonography in the diagnosis of hepatic metastasis from lung cancer and improve further the diagnostic accuracy. Methods The ultrasonography characteristics of 200 cases with hepatic metastasis from lung cancer were reviewed and analysed. Results One hudred and nineteen (59.5%) cases were multiple masses and 81 (40.5%) cases were single mass. The metastatic masses located in the right lobe of the liver more than in the left. The size varied from 0.5 cm to 9. 7cm. Majority cases were circular or similar circular shape. Fifty-three (26.5%) cases were hyper echoes and 98 (49.0%) cases were hypo echoes. 32 (16%) and 17 (8.5%) cases were similar echoes or mixed echoes respectively. Conclusion The ultrasonography of hepatic metastases from lung cancer varied. To master its peculiarity, it most could be diagnosed combined with clinical presentation definitely.
