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。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.
