节细胞神经瘤CT诊断与鉴别诊断

目的:探讨节细胞神经瘤的CT表现及诊断价值,提高对此病的认识及诊断的准确性。方法:回顾性分析12例经手术病理证实的节细胞神经瘤患者的CT及临床病理资料,男9例,女3例,年龄4~53岁,平均25.2岁。结果:节细胞神经瘤一般表现为边界清楚的类卵圆形肿块,常沿冠状轴生长,肿瘤可对邻近大血管包绕。CT平扫均为低至中等密度,其内散在点状钙化。增强扫描不强化或轻度强化,延迟扫描部分逐渐增强,病理上与肿瘤富含大量黏液基质相关。结论:CT扫描有助于提高节细胞神经瘤的诊断并可提供临床信息,但此病的最终诊断仍需要病理学检查。

CT diagnosis and differential diagnosis of ganglioneuroma

Objective To analyze the CT findings of ganglioneuroma for improving it s recognization and diagnostic accuracy. Methods 12 patient s with pathologically proved ganglioneuroma consisted of 9 males and 3 females ,aged 4 ~ 53 years with a mean of 25. 2 . CT scanning was perfomed in all cases. The clinical data and imaging findings were retro - spectively analyzed. Results Ganglioneuromas ap-peared as the well defined,oval along coronal axle,and the adjacent main vessels were partially wrapped. On CT plain scan the mass showed low or intermediate density. There was punctuate calcification in tumors and no enhancement or slight enhancement on contrast -enhanced CT. Dynamic enhancement studies showed a lack of early enhancement but gradual increasing which might correlate histologically with abundantmyxoid matrix. Conclusion CT is helpful in improving the diagnostic accuracy of ganglioneuromas and can provide more in-formation ,yet final diagnosis should be based on pathology examinations.
