  • Abstract
  • Look Inside

A 22-year-old woman was involved in a motor vehicle accident and suffered a craniofacial injury. The patient was treated conservatively with a diagnosis of cerebral contusion in the frontal base confirmed with MR images. When the patient regained consciousness one week after the accident, she had a complete form of bitemporal upper quad-rantanopia. A bone window level CT scan showed a linear fracture in the middle of the frontal base running longitudi-nally and extending posteriorly down to the sella turcica and clivus. Axial MR images parallel to the optic pathway revealed a T2 bright lesion in the anterior half of the optic chiasm.
