title: Multidirectional CT of the posterior fossa.
abstract: Computer tomography of the head using the standard views parallel to the orbitomeatal line, does not demonstrate the anatomy of the posterior fossa to the best advantage, because the slices pass obliquely through the brain stem and cerebellum. The cranial and caudal borders of the posterior fossa (tentorium and foramen magnum) are also cut obliquely. A series of slices lying in optimal anatomical planes are suggested. The results are discussed.
