肾上腺节细胞神经瘤8例的诊断和治疗

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例呈密度均匀或销不均匀肿块,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加权介呈不均匀高信号（相对于正常肝脏信号）。结论：（1）CT和MRI检查在肾上腺节细胞神经瘤术前诊断中有重要价值。（2）治疗主要领先外科手术。

The Diagnosis and Treatment of the Adrenal Ganglioneuroma

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.
