摘要
目的:探讨结节性硬化的临床和MRI诊断价值。方法:回顾分析11例结节性硬化症病例的临床和MRI影像资料。结果:病灶表现为脑组织内多发性形态不规则结节,散布于脑皮质、皮质下和脑室室管膜下;结节在T2WI像呈高或低信号,T1WI呈等或低信号,增强后结节不强化。结论:结节性硬化的头颅MRI表现具一定特征性,对早期诊断具有一定价值。
Objective:To investigate the clinical manifestation and the value of MRI diagnosis of tuberous sclerosis. Methods: The clinical and MRI manifestation of 11 tuberous sclerosis cases were retrospectively investigated. Results: The le sions were irregular nodules located in the brain cortex,subcortex and subependymal. The nodules showed high or low in tensity on T2WI and equal or low imensily on T1WI, without enhancemem reaction. Conclusion: Tuberous sclerosis shows characteristic signs on MRI,and so MRI is very valuable in its diagnosis in early periods.
