Abstract
Detailed anatomy of the brain stem and cervicomedullary junction can be accurately demonstrated with metrizamide computed tomographic cisternography. Specifically. surface anatomy is unusually well outlined. Nine distinct and easily recognizable levels of section are described: four levels in the medulla, three in the pons, and two in the mesencephalon. Surface features of the brain stem, fine details in the floor of the fourth ventricle, cranial nerves, and vascular structures are shown and discussed.
