目的:探讨CT对肾上腺肿瘤的诊断价值.材料与方法:回顾性分析94例经手术病理证实的各类肾上腺肿瘤,观察其CT征象,提出诊断和鉴别诊断要点.结果:醛固酮腺癌肿块小,密度低;皮质醇腺瘤中等大小,中等密度;肾上腺原性腺综合征肿块较大,密度均匀;无机能性腺瘤与神经节瘤相似表现为肿块较大,密度略低;肾上腺皮质腺癌肿块巨大,呈不规则低密度;肾上腺转移癌肿块较大,密度不均匀;嗜铬细胞瘤肿块较大,密度不均匀,强化明显.结论:CT对肾上腺肿瘤检出率高,在定性诊断上有重要参考价值,本组诊断符合率为84％.“,”Objective: To evaluate CT scan in dignosing of adrenal tumor. Materials and Methods: CT findings of vdrious athenal tumors in 94 pathaogically proved cases were analzed retrospectively, the key to the diagnosis and differential diagnosis was suggested. Results: Usually,aldostearone adenoma was low in dedrity and small in size, while cortisol adenoma was moderate in density and medium in size. Tumor producing adreno-gonadal syndrome was commonly large with homogeneous density. Similar to ganglioma, non-functional adenoma was large and slightly low in density. Adrenocortical adenocarcinoma was the largest one with irregular hypodensity. Metastatic careinoma was large and inhomogeneous in density. Pheochromocytoma was large, inhomogeneous in density and enhanced markedly after contrast administration Conclusion: CT scan is very helpful in detecting adrenal tumor and provides important information for qualitative diagenosis. The accurate dibec rate in thes group is 84 %.
