摘要
目的 :回顾分析 8例肾上腺节细胞神经瘤的临床资料 ,以提高对其诊断的水平。方法 :8例病例行 CT平扫肾上腺区 ,其中 4例加行 CT增强扫描 ,2例加做肾上腺区磁共振成像 (MRI)检查 ,对其影像学特点进行总结。结果 :8例经病理证实的肿瘤中 ,7例 CT平扫呈密度均匀、低于肌肉密度的肿块 ;增强扫描 4例呈密度均匀或稍不均匀肿块 ,低于或等于肌肉强化密度。MRI2例在冠状位 T1加权像表现为均匀低信号 ,轴位 T2加权像呈不均匀高信号 (相对于正常肝脏信号 )。结论 :1CT和 MRI检查在肾上腺节细胞神经瘤术前诊断中有重要价值。
Objective:To promote the accuracy of the diagnosis of the adrenal ganglioneuroma(AG), eight cases of AG proved by pathology were retr ospectively analysed. Methods:Noenhanced CT scanning were accomplished in 8 cases, 4 of w hich underwent contrst CT and 2 underwent MRI scan respectively. Their imaging f eatures were summarised. Results:Sevent cases showed a homogeneous mass with attenuation less t han that of muscle and four cases which underwent contrst-enhanced CT showed a homogeneous or mildly heterogenous mass with attenuation less than or equal to t hat of muscle. MRI imaging which were performed in 2 cases showed a homogeneous mass with signal intensity less than that of liver on T1-weighted MR. On T2-we ighted MR image the mass was heterogeneous with the predominant signal intensity greater than that of liver. Conclusion:(1)It was considered that CT a nd MRI play an important role in the diagnosis of the adrenal ganglioneuroma. (2 )The treatment is mostly dependent on surgical operation.
