创伤性基底节损害不常见,多数为或大、或小的血肿,通常是由于中、重度颅脑外伤中的剪力所致。严重脑外伤病人的CT扫描发现低密度病变的病例最近已有报告;但基底节区的且出现在轻度脑外伤后的低密度病变还未见报告。 作者在3年中收治了23例轻度颅脑外伤儿童病例,伤后立即行CT扫描,发现了基底节低密度病变。患儿年龄8个月～6岁半。其中5岁以下21例,3岁以下16例;男20例,女3例。伤后仅有3个患儿有意识改变,持续了几小时。每个患儿伤后即出现单侧肢体无力,以上肢较明显,但无一例继续恶化。除偏瘫外,10例患儿有中枢性面瘫、6例失 Traumatic damage to the basal ganglia is not common, mostly large, or small hematoma, usually due to moderate and severe traumatic brain injury due to shear. Low density lesions have been recently reported on CT scans of patients with severe brain trauma; however, there has been no report of low density lesions in the basal ganglia that appear after mild traumatic brain injury. The authors treated 23 children with mild craniocerebral trauma in 3 years. CT scans were performed immediately after the injury and low-density lesions of the basal ganglia were found. Children aged 8 months to 6 years and a half. Among them, 21 cases were under 5 years of age and 16 cases were under 3 years old. There were 20 males and 3 females. Only 3 children with injuries consciously changed and lasted several hours. Unilateral limb weakness in each child after injury, to more obvious upper limbs, but no one continued to deteriorate. In addition to hemiplegia, 10 cases of children with central facial paralysis, 6 cases lost
