重度未成熟儿致痉挛性脑瘫的MRI表现与分析

Magnetic Resonance Imaging in Premature Infants with Severe Spastic Cerebral Palsy: Performance and Analysis of 66 Cases

目的探讨重度未成熟儿致痉挛性脑瘫的MRI影像学特点。方法经临床诊断66例痉挛性脑瘫患儿,均行MRI颅脑检查。结果66例患儿颅脑MRI表现,脑室周围白质软化45例,伴随胼胝体发育不良18例,脑白质髓鞘发育延迟5例;弥漫性脑软化囊变并脑萎缩6例,局限性脑软化囊变并脑萎缩2例,脑先天发育畸形3例,脑外间增宽3例,宫内感染表现者2例。结论MRI检查重度未成熟儿致痉挛性脑瘫敏感性高,特征性强,可为临床治疗方案选择提供有价值的帮助。

Objective To investigate the characteristics of magnetic resonance imaging in premature infants with severe spastic cere bral palsy. Methods Cerebral MRI examinations were performed for 66 cases of clinically diagnosed infants with spastic cerebral palsy. Results 66 cases of infants by brain MRI showed periventricular leukomalacia in 45 cases, accompanied with corpus callosum hypoplasia in 18 cases and developmental delay of white matter myelin in 5 cases; diffuse cystic encephalomalacia and cerebral atrophy in 6 cases, limited cystic encephalomalacia and cerebral atrophy in 2 cases, congenital cerebral deformity in 3 cases, widened outside-brain in 3 cases, and performance of intrauterine infection in 2 cases. Conclusion MRI examination in premature infants with severe spastic cerebral palsy has the advantages of a high sensitivity and marked characteristics, which helps to provide valuable options in clinical treatment.
