目的探讨超声显像对肾上腺肿瘤的定位、定性诊断与鉴别诊断价值。方法对2003年1月-2009年1月125例疑为肾上腺肿瘤患者进行超声及CT检查,并经手术与病理证实。超声显像诊断后经手术与病理证实为嗜铬细胞瘤48例,肾上腺皮质腺瘤41例,皮质腺癌11例,肾上腺转移癌9例,髓样脂肪瘤8例,结节样增生2例,肾上腺结核4例,胰尾部肿瘤1例,肝脏肿瘤1例,肾上极肿瘤1例。结果肾上腺肿瘤的病理类型不同,声像图表现亦各不相同。超声显像定位诊断符合率为96.0%(120/125),定性诊断符合率为91.2%(114/125)。结论超声显像对肾上腺肿瘤的定位与定性诊断价值较大,可作为临床诊断的首选检查方法。
Objective To investigate the localization, qualitative diagnosis and differential diagnosis of adrenal tumors by ultrasound imaging. Methods From January 2003 to January 2009, 125 patients with suspected adrenal tumors were examined by ultrasound and CT, and confirmed by operation and pathology. Ultrasound imaging confirmed by surgery and pathology in 48 cases of pheochromocytoma, adrenal cortical adenoma in 41 cases, 11 cases of cortical adenocarcinoma, adrenal metastasis in 9 cases, myeloid lipoma in 8 cases, nodular hyperplasia in 2 cases , 4 cases of adrenal tuberculosis, 1 case of pancreatic tail tumor, 1 case of liver tumor and 1 case of suprarenal tumor. Results The pathological types of adrenal tumors were different, and the sonographic findings also varied. The coincidence rate of ultrasound imaging and localization was 96.0% (120/125), and the coincidence rate of qualitative diagnosis was 91.2% (114/125). Conclusion Ultrasound imaging of adrenal tumors localization and qualitative diagnosis of larger, can be used as the preferred method of clinical diagnosis.
