Case example demonstrating the use and application of the Utah Score for predicting cerebrovascular injury (BCVI). An 8-year-old boy involved in a motor vehicle accident who had a right temporal epidural hematoma necessitating evacuation had a Glasgow Coma Scale score of 10 and nonfocal neurological examination. He had a fracture through the carotid canal (A, arrow), no petrous temporal bone fracture, and no cerebral infarct on computed tomography. This patient is low risk with a Utah Score of 2, which yields a 6.7% probability of BCVI (Table 2). Computed tomographic angiography demonstrated no injury (B, arrow).
