摘要
目的探讨彩色多普勒超声诊断肾上腺转移性肿瘤的临床应用价值。方法回顾性分析52例经手术病理、CT、核磁共振相印证的转移性肾上腺肿瘤的超声资料。结果转移性肾上腺肿瘤呈圆形、椭圆形或不规则形,大小相差悬殊,肿块小于3cm者多为均质低回声,大于3cm者为不均匀强弱不等回声,边界较清,肿块内血供不丰富,可探及点状血流信号,为低速高阻动脉血流。本组4例误漏诊病例中,2例误诊为右肝肿瘤;2例因左侧肾上腺肿瘤小于1.5cm未发现而漏诊。彩色多普勒超声诊断肾上腺转移性肿瘤正确率为92.31%。结论超声可以从病灶大小、有无包膜和血流情况等征象来诊断和鉴别诊断肾上腺肿瘤。
Objective To explore the diagnostic value of color Doppler in metastatic adrena tumor. Methods The results of Doppler examination in 52 patients with metastatic suprarenal tumor confirmed by operation, pathology, CT and MRI were analyzed ret- rospectively. Results The metastatic adrena tumors were round, oval - shape or irregularly shape and their size was disparitydifferent. The tumors which diameter was less than 3 cm were low iso- echo; while tumors which diameter was more than 3cm were poor iso - echo, distinct margin and not abundant blood supply, at the same time the punctiform, low resistance, high velocity and artery - like flow signals were detected in them. The qualitation diagnostic accuracy of color Doppler is 92.30%, which suggest the adrena tumor can be diagnosed and antidiastoled by color Doppler through the size, envelope and blood flow signal. Conclusion Color Doppler, which is a direct, rapidly and high diagnostic accuracy method, provides valuable imaging message to clinical diagnose and it should be the first imaging choice.
