结节性硬化的影像学诊断分析

目的分析结节性硬化的CT及MRI影像学特征,为该病的临床诊断提供科学依据。方法回顾性分析17例结节性硬化患者的CT及MRI影像资料。结果17例均表现为沿室管膜下分布结节,5例同时伴有皮层及皮层下结节,1例合并有室管膜下巨细胞星彩细胞瘤。CT对钙化结节显示比较有优势,而MRI对非钙化性病灶,尤其是皮层及皮层下脑白质内的病灶更具有优势。结论结节性硬化的CT及MRI表现具有一定的特征性,两者结合能增加病灶的检出率,对该病的临床诊断和评价中枢神经系统损害具有要意义。

Objective To analyze the CT and MBI imaging characteristics of tuberous sclerosis to provide the scientific basis for the clinical diagnosis of the disease.Methods The CT and MRI imaging data of 17 patients with tuberous sclerosis were retrospectively analyzed.Results All 17 cases showed nodules distributed along the sub ependyma,5 cases were accompanied by cortical and subcortical nodules,and 1 case had subependymal giant cell astrocytoma.CT had advantages in showing calcified nodules,while MRI had advantages in non-calcified lesions,especially in the cortex and subcortical white matter.Conclusion The CT and MRI manifestations of tuberous sclerosis have certain characteristics,and the combination of the two can increase the detection rate of the lesion,which is of great significance for the clinical diagnosis of the disease and the evaluation of central nervous system damage.
