摘　　要：目的探讨恶性肿瘤患者中偶发性肾上腺肿瘤的诊断方法。方法对2001年6月至2009年1月我院收治的78例恶性肿瘤患者中偶发性肾上腺肿瘤的临床资料进行回顾性分析。结果 78例患者中肾上腺偶发瘤的大小为0.8～7.0 cm,42例手术治疗者中术后病理诊断为良性病变35例(35/42,83.3%),恶性肿瘤均为转移癌(7/42,16.7%)。其中平扫CT值≤30 HU、肿瘤直径≤4.0 cm的27例肾上腺偶发瘤均为良性病变,15例平扫CT值>30 HU、肿瘤直径>4.0 cm肿瘤中7例(46.7%)为转移癌,两组恶性肿瘤所占比例差异有统计学意义(P<0.01)。结论对于恶性肿瘤患者的偶发性肾上腺肿瘤,肿瘤的平扫CT值>30HU且直径>4.0 cm时转移癌的可能性较大,肿瘤的平扫CT值≤30 HU且直径≤4.0 cm时一般为良性肿瘤。Objective To evaluate the diagnostic methods of adrenal incidentalomas in the patients with malignant tumors.Methods The clinical data of 78 cases of adrenal incidentalomas in patients with malignant tumors admitted from June 2001 to January 2009 were analyzed retrospectively.Results Among the 78 patients,the size of adrenal incidentalomas was 0.8 cm to 7.0 cm.42 cases underwent surgical management.Among them,35 were benign（35/42,83.3%）,and all the malignant tumors were metastatic cancer（7/42,16.7%）.The 27 lesions with the unenhanced CT attenuation ≤30 HU and diameter ≤4.0 cm were all benign.Among the 15 lesions with the unenhanced CT attenuation 30 HU and diameter 4.0 cm,7 were metastatic carcinoma（46.7%）,there was significant difference in the percentage of malignant tumors in these two groups（P 0.01）.Conclusion For the adrenal incidentalomas in patients with malignant tumors,if the unenhanced CT attenuation of the adrenal tumor was over 30 HU,and its diameter is over 4.0 cm,it might be metastatic carcinoma.In contrast,if the unenhanced CT attenuation of the adrenal incidentaloma is less than 30 HU,and its diameter is less than 4.0 cm,it might be benign.
