We report a case of a 15-year-old boy who presented to our institution with left-sided weakness and slurred speech. He had a history of medulloblastoma diagnosed at 3 years of age, status postsurgical resection and craniospinal radiation. Magnetic resonance imaging (MRI) of brain revealed a right paramedian pontine infarction, suspected secondary to late-onset radiation-induced vasculopathy of the vertebrobasilar system. Radiation to the brain is associated with increased incidence of ischemic stroke. Clinicians should have a high index of suspicion for stroke when these patients present with new neurologic symptoms.
我们报告一例15岁男孩，他因左侧肢体无力和言语不清前来我院就诊。他在3岁时被诊断为髓母细胞瘤，接受过手术切除和颅脊髓放疗。脑部磁共振成像（MRI）显示右侧脑桥旁正中梗死，怀疑继发于迟发性椎基底系统放射性血管病。脑部放疗与缺血性卒中发生率增加有关。当这些患者出现新的神经系统症状时，临床医生应高度怀疑卒中。
