22例肾上腺肿瘤的B超诊断分析

目的:通过分析肾上腺肿瘤的B超、CT检查结果,并与手术病理对照,探讨误诊原因,评价B超对肾上腺肿瘤的诊断价值。材料和方法:本文报告了肾上腺肿瘤22例,手术前均进行了超声、CT检查,仪器使用GERT2800、Dornier Perferma,探头频率3.5MH_2。结果:22例肾上腺肿瘤均为单发,其中皮质腺瘤10例、嗜铬细胞瘤8例、皮质腺癌2例、肾上腺转移癌1例、肾上腺囊肿1例,超声定位符合率81.8％,定性符合率54.5％;CT定位符合率100％,定性符合率90.9％。结论:B超可作为临床疑为肾上腺肿瘤的常规检查。由于肾上腺肿瘤声像图缺乏特异性,必须结合临床病史和其他检查才能作出松为正确的诊断。

Analysis of B - Ultrasonographic Diagnosis of Adrenal Tumors

Objective: In this paper, the ultrasonic and CT examinations for adrenal tumors were analysed and compared with operation and pathology , the causes of misdiag-nosis discussed, and the diagnostic value of B - Ultrasonography in adrenal tumors evaluated. Materials and Methods: 22 cases of adrenal tumors were reported. They were all examined by B - ultrasonography and CT before operation . The ultrasonic detective ap-paratuse was GERT 2800, Dornier performa. The frequency of probes was 3. 5MHZ. Results : Adrenal tumors were single in all the patients. Of 22 cases, adrenocortical adenoma -was observed in 10, pheochromocytoma in 8, adrenocortical adenocarcinoma in 2, a-drenal metastatic carcinoma in 1, adrenal cyst in l.The locational accuracy rate was 81. 8% by ultrasound and 100%by CT, The qualitative accuracy rate was 54. 5% by ultrasound and 90. 9% by CT. Conclusion: B - ultrasonography could be used as a routine examination for suspected adrenal tumors in clinic. As the sonogram of adrenal tumors lacks specificity, the diagnosis should be made in combination with case history and other examinations.
