An 11-year-old girl developed cerebellar infarction presenting as a posterior fossa mass lesion after stretching and flexing her neck. Cerebral angiography demonstrated irregular narrowing of the right vertebral artery at the C2 level and x-rays of the upper cervical spine showed atlantoaxial subluxation with os odontoideum. She underwent surgical decompression with removal of infarcted tissue. The cerebellar infarction probably resulted from occlusion of the vertebral artery, followed by brain swelling due to recanalization.
一名11岁女孩在颈部伸展和弯曲后出现小脑梗死，表现为后颅窝肿块病变。脑血管造影显示C2水平右侧椎动脉不规则狭窄，上颈椎X线片显示齿突游离小骨导致寰枢椎半脱位。她接受了手术减压并切除梗死组织。小脑梗死可能是由于椎动脉闭塞，随后再通导致脑肿胀所致。
