摘　　要：目的:探讨肾上腺肿瘤的CT误诊原因。方法:对15例经手术病理证实的肾上腺肿瘤CT误诊病例的位置、大小、形态、密度及强化等表现进行统计分析。结果:15例误诊病例中,7例为肾上腺嗜铬细胞瘤(46.67%),3例为肾上腺无功能性腺瘤(20%),2例为肾上腺黏液性囊腺瘤(13.33%),1例为肾上腺癌(6.67%),1例为肾上腺转移瘤(6.67%),1例为肾上腺神经母细胞瘤(6.67%),均出现定位诊断错误。结论:肾上腺肿瘤CT误诊原因主要是定位困难。加强对肾上腺肿瘤CT征象的认识,结合临床资料可减少误诊率,提高诊断的准确率。Objective： To explore the influence factors of CT misdiagnosis of adrenal tumor. Methods： Made statistical analysis of CT manifestations like location, size, shape, density and enhancement appearance of 15 cases of adrenal tumor confirmed by surgery and pathology. Results： Among the 15 cases, 7 were adrenal phaeochromocytoma（46.67%, 7/15） ; 3 were adrenal non-functional adenoma（20%,3/15） ; 2 were adrenal mucous cystoadenoma（13.33%, 2/15） ; 1 was adrenal carcinoma（6.67%, 1/ 5）; 1 was adrenal metastatic（6.67%,1/5）; 1 was adrenal neuroblastoma（6.67%, 1/5）. All the eases were amiss localization diagnosed （100%）. Conclusion： The location of CT misdiagnosis of adrenal tumor is difficult. Improving the CT manifestations of the disease and referring to clinical data can reduce the misdiagnosis rate and raise the accuracy rate.
