Vertebrobasilar occlusion following minor trauma in an 8-year-old boy.

An 8-year-old boy developed seizures and coma 2 days after a trivial bicycle accident. Computed tomography failed to show pathology. Magnetic resonance imaging of the head showed infarction of the pons and right cerebellum. Angiography showed occlusion of the right vertebral and basilar arteries. Minor traumatic injuries to the cervical spine may result in vertebrobasilar occlusion. The neurologic manifestations of this disorder and emergency department diagnosis and management are discussed.
