[Computerized tomography in cerebellar atrophy].

Among 5680 patients who had CT cranial scans at the Radiological Service of the Hospital of Pordenone we selected by their histories and clinical findings and CT images 31 patients showing the signs of a cerebellar atrophic process. We compared CT scans with clinical symptoms; we found a correlation in 71% among CT abnormalities and clinical findings; in 22.5% CT showed an infratentorial atrophy, but clinical symptoms were absent; in 6.5% the CT scans were normal, although was present a cerebellar syndrome. We conclude that CT is an important and significative method in the diagnosis of posterior fossa degeneration, taking so the place of pneumoencephalography.
