Abstract
Fifty patients with posterior fossa intra-axial tumors were evaluated by computed
tomography and the results compared with routine skull films, radionuclide brain scanning,
vertebral angiography, and cerebral air studies. The routine skull series was found
to be of little benefit. Computed tomography was more sensitive than the radionuclide
brain scan in detecting all of the lesions except astrocytoma, for which sensitivity
was comparable. Angiography was the most sensitive means of detecting hemangioblastoma,
and was the only reliable radiographic method of differentiating hemangioblastoma
from astrocytoma, Cerebral air studies were the most sensitive and specific means
of evaluating brainstem gliomas.
