Evaluations of roentogenologic findings of the cerebellopontine angle disease

Abstract

Various approaches such as pneumoencephaloroulette tomography, scintiscanning, CT scanning, cisternal myelography are available for radiological examination of lesions of the posterior cranial fossa, and in some cases, these examinations are partinent for a neurotological diagnosis. We evaluated radio-logical findings in 25 patients with the cerebellopontine angle lesion and the results are as follows :
In some cases without clear findings in Stenvers' projection nor detectable nystagmus, CT scanning was useful.
For differential diagnosis of a non-serious cerebellopontine angle lesion such as cystic arachnitis, pneumoencephalo-roulette tomography proved to be useful.
The cisternal myelography was not evaluated herein.
