目的 分析原发性肾上腺皮质腺癌的CT诊断特征。方法 收集 1 990～ 1 999年间经手术与病理证实的 1 3例腺癌的CT和临床资料。结果 功能性皮质腺癌 8例 ,无功能皮质腺癌 5例。肿瘤体积均较大 ,>5cm者 1 0例。CT表现密度不均 ,9例有坏死 ,实性部分强化明显。边界光整 6例 ,边缘毛糙或不规则 7例 ,其中 3例有局部浸润或远处转移。结论 结合临床特征 ,CT可诊断绝大多数有功能皮质腺癌 ,而无功能皮质腺癌则不易与嗜铬细胞瘤鉴别 ,确诊需依赖病理诊断
Objective To analyze the CT diagnostic features of primary adrenocortical adenocarcinoma. Methods CT and clinical data of 13 cases of adenocarcinoma confirmed by surgery and pathology between 1990 and 1999 were collected. Results Functional cortical adenocarcinoma in 8 cases, 5 cases of non-functioning cortical adenocarcinoma. Tumor size are larger,> 5cm were 10 cases. CT showed uneven density, necrosis in 9 cases, the solid part of the obvious enhancement. Six cases were treated by border radiofrequency, seven cases with rough or irregular edges, of which three cases had local infiltration or distant metastasis. Conclusion Combined with clinical features, CT can diagnose the vast majority of functional cortical adenocarcinoma, while non-functional cortical adenocarcinoma is not easy to identify with pheochromocytoma, the diagnosis depends on the pathological diagnosis
