目的：研究肾上腺皮质癌声像图特征及其与病理结构的相关性。方法：回顾性分析经二维及彩色多普勒超声诊断的并经手术、病理证实的１１例肾上腺皮质癌患者。结果：本组肾上腺皮质癌声像图特征：等回声组所占比例最大，占４５５％（５／１１）；强回声组占２７３％（３／１１）；低回声组占１８２％（２／１１）；混合回声占９１％（１／１１）。Ｂ超定位诊断符合率为９０９％（１０／１１）；定性诊断符合率为５４５％（６／１１）。结论：１肾上腺皮质癌的声像图特征为：①肿瘤以等回声为主的较大肿瘤多见，本组均大于５６ｃｍ；②肿瘤形态多样，以不规则形及分叶状多见；③彩色多普勒血流显示瘤内及瘤周血流丰富；④肿瘤内多见液化坏死。２与病理结构的相关性为肿瘤内回声的高低与肿瘤细胞的大小、排列情况、血管纤维组织及坏死等病理结构含量多少有关
Objective: To study the features of sonographic features of adrenocortical carcinoma and its correlation with pathological structures. Methods: A retrospective analysis of 11 patients with adrenal cortical carcinoma diagnosed by 2D and color Doppler ultrasound and confirmed by surgery and pathology. RESULTS: The adrenocortical carcinoma features in this group were the most common, accounting for 45.5% (5/11) of the echogenic group, 27% and 3% (3/11) of the strong echo group, and 18% of the low echo group. 2% (2/11); mixed echoes accounted for 91% (1/11). The diagnostic accuracy of B-ultrasound was 90.9% (10/11); the diagnostic accuracy of qualitative diagnosis was 54.5% (6/11). Conclusion: 1 The features of the adrenal cortical carcinoma are as follows: (1) Larger tumors with predominance of echoes are more common in this group, which are all greater than 5-6 cm; (2) The tumors are diverse in shape, irregular and lobulated. See; 3 color Doppler blood flow shows intratumoral and peripheral blood flow; 4 tumor liquefaction necrosis. 2. The correlation between pathological structure and the level of the echo structure in the tumor is related to the size of the tumor cells, the arrangement of the tumor cells, and the amount of pathological structures such as vascular fiber tissue and necrosis.
