摘　　要：目的探讨肾上腺节细胞神经瘤CT表现特征与病理组织学关系,提高对肾上腺节细胞神经瘤的诊断符合率。方法搜集经手术病理证实的肾上腺节细胞神经瘤17例,回顾性分析其临床资料、CT表现与病理特征。结果本组17例病例中,均为单发。16例均为实性团块(其中内有细碎钙化灶2例),1例呈完全囊性。≥5cm者占10例(最大者约9cm)。肿物呈圆形或卵圆形12例,分叶状2例,不规则形3例。右侧10例,左侧7例。17例中有3例对周边脏器及血管推移,2例包绕邻近血管,其余与周围脏器分界清晰。增强扫描动脉期14例无明显强化,3例轻度强化;静脉期及延迟期14例呈不均质或间隔状强化,2例轻度强化;1例无强化。结论肾上腺节细胞神经瘤具有一定的影像特征,与其病理学表现密不可分,了解其特征表现有利于提高影像诊断率。Objective To discuss the correlation of CT features with pathological results in ganglioneuroma ,and to im‐prove its diagnostic accuracy .Methods A total of 17 cases with pathologically‐proved ganglioneuroma were collected .The clinical data ,CT examinations and pathological features were retrospectively analyzed .Results Of the 17 cases with adre‐nal ganglioneuroma ,all were single lesion .16 cases were solid masses （including small calcification in 2 cases） ,1 case showed cystic lesions .Greater than or equal to 5 cm accounted for 10 cases （maximum of about 9 cm） .Lesions were round or oval in 12 cases ,lobular in 2 cases ,irregular in 3 cases .There were 10 cases in the right side ,7 cases in the left .There were 3 cases of peripheral organs and vessels passing in 17 cases ,2 cases of wrap around the adjacent vessels and sur‐rounding organs ,the remaining was clear demarcation .Arterial phase enhanced scanning showed no enhancement in 14 pa‐tients ,mild enhancement in 3 cases .Venous phase and delayed phase in 14 cases showed heterogeneous or interval like en‐hancement ,mild enhancement in 2 cases ,1 without enhancement in 1 case .Conclusion Adrenal ganglioneuroma has well correlation of CT features with pathologic characteristics ,which are helpful for the diagnosis .
