【摘要】：目的:探讨儿童节细胞神经瘤的CT、MRI特征,旨在提高对其认识。方法:回顾性分析病理证实的38例儿童节细胞神经瘤的CT、MRI资料。结果:38例患儿中男女比例为1:1.8,平均年龄6.07±2.47岁。肿瘤位于后纵隔14例(36%),腹膜后间隙14例(36%),肾上腺8例(21%),颈部及盆腔各1例。肿瘤表现为类圆形、边界清晰的肿块,平扫CT图像显示大部分肿瘤表现为均匀低密度,CT值为22~38HU(平均30.5HU);MRI扫描图像显示,病灶于T1WI呈等信号为主或稍低信号,T2WI呈不均匀高信号,增强扫描动脉期病灶以不强化为主,门脉期可见轻中度强化。结论:节细胞神经瘤的CT及MRI表现具有一定的特征性,CT平扫均匀低密度,T2WI上呈不均匀高信号,肿瘤增强扫描后动脉期无强化,门脉期可见轻度或中度强化。
[Abstract]:Objective: to investigate the CT MRI features of International Children's Day's cell neuroma. Methods: the CT MRI data of 38 cases of International Children's Day's cell neuroma confirmed by pathology were analyzed retrospectively. Results the ratio of male to female was 1: 1.8 in 38 children with a mean age of 6.07 卤2.47 years. The tumor was located in the posterior mediastinum in 14 patients with retroperitoneum. There were 14 cases in the space, 8 cases in the adrenal gland, 1 case in the neck and 1 case in the pelvic cavity. On plain scan CT images showed that most of the tumors showed homogeneous low density CT value of 22 ~ 38 HUU (mean 30.5 HUU MRI). The lesions showed iso-signal on T _ 1WI or heterogeneous hyperintensity on T _ 2WI. Conclusion: the CT and MRI features of ganglioneuroma are characterized by non-enhancement in arterial phase and uneven hyperintensity on T _ 2WI on homogeneous low-density CT scan in ganglion cell neuroma. Conclusion: the CT and MRI findings of ganglion cell neuroma are characterized by non-enhancement in arterial phase and mild and moderate enhancement in portal phase. There was no enhancement in arterial phase and mild or moderate enhancement in portal phase after tumor enhancement.
