Computed tomography in cerebellar atrophic processes

Abstract

Forty-six patients with cerebellar atrophy were identified by review of CT scans of 7,500 patients. Independent examination of a separate file of the same group disclosed 49 patients whose history indicated cerebellar degeneration. Forty-three patients were in both groups indicating excellent correlation between CT abnormality and clinical cerebellar signs. Three patients with CT cerebellar atrophy failed to show clinical cerebellar signs, and 6 had clinical signs without evidence of changes on CT. Specific anatomic correlation was suggested in 10 of 13 patients with predominantly midline cerebellar CT abnormalities, and in 3 with olivopontocerebellar degeneration clinically who showed brainstem and cerebellar atrophy.
