目的 探讨超声检查对肾上腺无功能肿瘤的诊断价值。方法 对照分析 10 6例肾上腺无功能肿瘤的超声检查和手术病理结果。结果 10 6例患者中 ,超声诊断真阳性 10 3例 ,真阴性、假阳性、假阴性各 1例 ,敏感性、特异性、准确性分别为 99.0 %、5 0 .0 %和 98.1%。肾上腺无功能肿瘤呈逐年增多趋势 ,被超声首次检出者为 77.9%。肿瘤从小到大依次为腺瘤、嗜铬细胞瘤、神经鞘瘤、髓样脂肪瘤、神经节细胞瘤、腺癌。各种肿瘤的大小有极显著性差异。髓样脂肪瘤以高回声为特征 ,易与其他肿瘤鉴别 ,其余肿瘤声像图交叉现象严重。较大的嗜铬细胞瘤、神经鞘瘤常有液化囊变表现 ,腺癌常为不均匀回声。结论 超声检查是肾上腺无功能肿瘤定位诊断首选的可靠的方法 ,并对鉴别肿瘤类型有一定帮助。
Objective To investigate the diagnostic value of ultrasonography in non-functional adrenal tumors. Methods Controlled analysis of 106 cases of adrenal non-functional tumor by ultrasound and surgical pathology results. Results One hundred and three cases of true positive, false negative and false negative were diagnosed by ultrasound. The sensitivity, specificity and accuracy were 99.0%, 5.0% and 98.1% respectively. Adrenal non-functional tumors showed a trend of increasing year by year, the first detected by ultrasound was 77.9%. Tumors from small to large followed by adenoma, pheochromocytoma, schwannoma, myeloid lipoma, ganglioneuroma, adenocarcinoma. The size of various tumors have very significant differences. Myeloid lipoma with high echo is characterized by easy identification with other tumors, the remaining tumor sonogram cross phenomenon is serious. Larger pheochromocytoma, schwannoma often cystic fluid performance, adenocarcinoma often uneven echo. Conclusion Ultrasonography is the first choice and reliable method for the diagnosis of adrenal non-functional tumor, and it is helpful to identify the type of tumor.
