磁共振早期诊断围产期窒息性脑瘫痪

目的：研究围产期窒息性脑性瘫痪患儿颅脑形态学病理变化。方法：围产期窒息患儿20例，男15例，女5例。生后第7—10天和第5—6月，进行两次头颅磁共振成像（MRI）检查。结果：5例患儿存在颅脑形态学异常，临床均表现为脑性瘫痪。新生儿期发现缺血缺氧性脑病1例，颅内出血4例。后者均存在脑实质出血，其中合并脑室内出血1例，合并蛛网膜下腔出血3例。婴儿期追踪复查MRI发现脑室周围白质软化症1例，脑萎缩2例，慢性血肿──脑内囊腔形成2例。结论：MRI可早期诊断国产期窒息性脑性瘫痪。

Early Diagnosis by Magnetic Resonance Imaging for Cerebral Palsy Caused by Perinatal Asphysia

To search the morphological changes in cefebral palsy caused byperinatal asphysia with the magnetic resonance imaging (MRI). Methods 20 newborns withPerinatal asphysia (15 males and 5 females)were examined with head MRI at the age of 5 - 7 daysand 5-6 months respectively. Results Cerebral morphological abnormality was found in 5 patients(25 % ) by MRI. In neonatal stadium, 1 patient was found with hypoxia-ischemic encephalopathy,and 4 with cerebral hemorrhage. All these 4 cases were with intraparenchymatous hemorrhage,among them, 1 wsa in combination with intraventricular hemorrage, and 3 with subarachnoidhemorrhage. In infantile stadium, 1 patient was found with Periventricular leukomalacia, 2 withencephaloatrophy, and 2 with chronic intraparenchymatous hetnatoma. Conclusion Head MRIcould early diagnose the cerebral morphological abnormality of cerebral palsy caused by perinatalasphysia.
