肾上腺皮质癌超声与病理相关性研究

A Study of Correlation of Ultrasound with Pathology in Adrenal Cortex Carcinoma

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１４例肾上腺皮质癌患者。结果：１４例病例全部经超声与病理分析研究表明，等回声组所见比例最大，占４３％（６／１４）；强回声组占２９％（４／１４）；低回声组占１４％（２／１４）；混合回声２例占１４％。Ｂ超定位诊断符合率为９３％（１３／１４）；定性诊断符合率为５７％（８／１４）。结论：①肾上腺皮质癌的声像图特征为：肿瘤是以等回声为主的较大肿瘤，本组均大于７．６ｃｍ；肿瘤形态多样，以不规则形及分叶状常见；彩色多普勒血流显示瘤内及瘤周血流丰富；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 feature of ultrasound imaging and the correlation with pathologic structure in adrenal cortex carcinoma.Method:The retrospective study was done in 14 patients with adrenal cortex carcinoma diagnosed by two dimensional and color doppler sonography and confirmed by pathology.Results:The results after study of ultrasound analysis and pathology indicated that the group of equal echo was account for 43%(6/14),the group of high echo 29%(4/14),the group of low echo 14%(2/14),and the group of mixed echo 14%(2/14).The rate of coincidence of location diagnosis was 93%(13/14),and the rate of coincidence of qualification was 57%(8/14).Conclusion:①The feature of ultrasound imaging in adrenal cortex carcinoma was:that the tumor was big one mainly with equal echo,more than 7.6cm in diameter in present study;that the tumor had a varying shape,commonly with irregular and multi lobe shape;that detection of blood flow of color dopper sonography showed that the tumor and the surrounding region of the tumor had a plenty of blood flow supply;that the liquid necrosis inside the tumor was seen frequently.②The correlation study demonstrated that the different echo in tumor was correlated with size and arrangement of tumor cells,the contents of pathologic structure of vascular and fibril tissues and necrosis.
