      【摘要】 目的 分析儿童节细胞神经瘤的CT表现，提高对其诊断的准确性。方法 回顾性分析经手术病
理证实的6例儿童节细胞神经瘤的CT表现，其中5例患儿行增强扫描。结果 3例病灶位于肾上腺，2例位于左
侧后纵隔，1例位于右侧后纵隔，病灶主要表现为境界清晰类圆形肿块，部分向周围组织嵌入性生长，CT平扫时
密度较低，其中4例出现散在点线钙化，增强后病灶轻度强化甚至局部不强化，部分渐进性强化。结论 儿童节
细胞神经瘤CT平扫及增强扫描具有一定的特征性，可提高临床诊断率。

【Abstract】 Objective To investigate the features of the ganglioneuroma in childhood on CT, in order to improve
the accuracy of diagnosis. Methods CT findings of 6 patients with ganglioneuroma proved pathologically were reviewed
retrospectively. Enhanced scan were performed in 5 cases. Results Among the 6 cases, lesions of 3 cases were located in
adrenal, with 2 in left posterior mediastinum and 1 in right posterior. The lesions were mainly characterized as well-defined
and round mass, and showed a tendency of wedging into the space of surrounding organization. The attenuation of lesions
was slightly low on plain CT. Multiple punctate calcifications could be observed in 4 lesions. After contrast injection, the le-
sions enhanced mildly or did not enhance, with the attenuation partly increasing with time. Conclusion The CT features
of ganglioneuromas are typical, which are helpful in improving the diagnostic accuracy.
