小儿颅脑外伤性腔隙性脑梗死的CT表现

目的探讨CT在小儿颅脑外伤性腔隙性脑梗死诊断中的价值及其特征。方法回顾性分析35例小儿颅脑外伤性腔隙性脑梗死的CT资料。结果本组患儿梗塞灶全部位于基底节区,31例合并基底节区点状钙化。伤后10～30d第3次复查,仅有4例病灶呈软化灶状态。结论本病多发于婴幼儿,梗塞部位多位于基底节区且多伴点状钙化。CT检查发现梗塞灶的最佳时间为伤后1～4d,动态CT检查不仅可以发现梗塞灶,而且还可观察其发展过程。

CT diagnosis of traumatic cerebral lacunar infarction in children

Objective To evaluate CT findings and the diagnosis of traumatic lacunar infarction.

There were malacia foic in 4 cases by follow-up cranial CT scanning four days to one month after head injury. Conclusions The disease often occurred in infants after minor head injury, in- farctions are common in the basal ganglia cerebral which was associated with lenticular calcifications lesion.
