摘要: 目的 探讨遗传性痉挛性截瘫伴薄型胼胝体(HSP-TCC)的特点。方法 对3例HSP-TCC患者的临床、电生理及头颅MRI资料进行回顾性分析,结合文献分析其遗传特点。结果 3例患者均以双下肢僵硬及行走困难起病,表现为双下肢痉挛无力,合并智力下降。2例神经电生理提示双下肢肌肉神经源性受损,1例电生理提示周围神经受损。智能检测均提示智力缺损。头颅MRI均显示胼胝体变薄,发育不良。目前对HSP-TCC进行了很多基因研究,其中一个遗传位点位于染色体15q13-15区域,但研究也发现一些HSP-TCC家族的发病与该遗传位点并无关系。结论 HSP-TCC是一种常染色体隐性遗传的复杂型HSP,伴有认知功能障碍,影像学提示胼胝体发育不良,电生理可提示神经源性受损。

Abstract: Objective To explore the characteristics of hereditary spastic paraplegia with thin corpus callosum (HSP-TCC). Methods Clinical, electrophysiological, MRI features of 3 patients with HSP-TCC were reported. The genetic characteristics were reviewed. Results 3 patients revealed difficulty in walking, slowly progressive weakness, spasticity of the lower limbs and mental impairment. The electromyogram in 2 cases showed neurogenic damage in lower limbs muscle, and 1 case showed peripheral nerve damage. Cerebral MRI showed an extremely thin corpus callosum on sagittal image. The locus of 15q13-15 has been identified for HSP-TCC, but some HSP-TCC families have not been linked to this locus.Conclusion HSP-TCC is a common subtype of complicated HSP inherited by autosomal recessive mode. Brain MRI showed extremely thin corpus callosum. Electromyogram many reveal neurogenic damage.
