摘要
目的:分析结节性硬化症的CT和MRI表现。方法:20例经病理及临床证实的结节性硬化病例进行头颅CT和MRI检查,分析其影像学改变。结果:结节性硬化的影像学表现:①室管膜下结节;②脑白质异常;③皮质结节;④室管膜下巨细胞星形细胞瘤;⑤囊状异常信号。结论:CT发现钙化结节有其特异性,MR检查T1WI发现室管膜下结节敏感,T2WI发现白质异常信号较为敏感,FLAIR序列显示皮质结节更为清晰。
Objective： To analyze CT and MRI characteristic features of tuberous sclerosis complex. Methods ： 20 pathologically and clinically proven patients with tuberous sclerosis complex with head CT and MRI scanning. Results： The main imaging findings on CT and MRI：①subependymal nodules;②the abnormal findings of white matter;③cortical tubers;④subependymal giant cell astrocytoma;⑤capsular abnormal signals. Conclusion ： CT is specified to nodules calcification. T1WI is sensitive to the subependymal nodules while T2WI is sensitive to the white matter changes and FLAIR sequence shows cortical tubers more clearly.
