【摘要】 目的 通过分析14例缺氧缺血性脑损伤所致脑瘫的MR成像特点及临床表现，讨论了该病的MRI表现与临床表现的相关性，以及MRI表现的病理损伤机制。方法 对14例缺氧缺血性脑损伤所致脑瘫患儿行MR检查，在T1WI及T2WI上对大脑皮层及皮层下白质、深部白质、基底节、丘脑、以及脑室和蛛网膜下腔等部位进行观察。结果 14例患儿均有癫痫发作及不同程度的智能发育障碍。其中3例MRI表现为皮层下白质软化，临床表现为痉挛性四肢瘫，上下肢受累程度相同。5例MRI表现为矢旁白质软化，临床表现为痉挛性四肢瘫，上肢较下肢重。6例MRI表现为室周白质软化，临床表现为痉挛性双瘫，下肢较上肢重。另外，14例患儿有3例MRI显示基底节损害，伴发锥体外系症状。结论 缺氧缺血性脑损伤所致脑瘫的MRI表现同临床表现具有相关性，并且不同的MRI表现有其特定的病理损伤机制。

    【Abstract】 Objective To study the MR findings and its relationship with clinical manifestions of cerebral palsy caused by hypoxic-ischemic brain damage.The pathological mechanisms of MR findings were also explored.Methods The MR findings of14patients with cerebral palsy caused by hypoxic-ischemic damage were studied retrospectively and correlated with clinical findings.All those patients underwent MRI.Cerebral cortex and subcortical white matter ......
