摘　　要：目的分析肾上腺节细胞神经瘤的影像学特点，提高对该病的认识及诊断。方法回顾性分析经手术和病理证实的12例肾上腺节细胞神经瘤的影像学表现，研究其影像表现与病理的相关性。结果11例发生在右侧肾上腺，1例发生在左侧肾上腺。10例行B超检查，均表现为肾上腺低回声肿块，其中4例肿块内部见强回声，伴后方衰减，病理显示为钙化；10例CT检查示肿瘤呈类圆形或椭圆形，少数呈不规则分叶状，轮廓光整，平扫呈均匀稍低密度，CT值28-46Hu，6例伴散在细点状钙化，增强后肿瘤呈不均匀轻至中度强化；2例磁共振成像检查示肿瘤呈类圆形，T1WI呈均匀稍低信号，T2WI呈不均匀稍高信号。结论肾上腺节细胞神经瘤影像学表现具有一定特征性，可在术前作出诊断及鉴别诊断。Objective To investigate the imaging features of adrenal ganglioneuroma and improve the diagnosis of the disease. Methods Imaging appearance and clinical pathological data of 12 cases of primary adrenal ganglioneuroma were retrospectively analyzed. Results Eleven lesions were found in the right adrenal gland and 1 case in the left. Echogenic focus with associated acoustical shadow were found in 4 cases which was pathologically confirmed calcification. CT attenuation of the tumor was homogeneouely low, the CT value was about 28~46 Hu, and sand calcification was found in 6 cases, and the mass had a linear enhancement at the arterial and venous phase. Conclusion The adrenal ganglion- euroma has some characteristic imaging appearance.h is possible to make correct diagnosis and differential diagnosis before operation.
