CT findings in progressive supranuclear palsy.
Computed tomographic (CT) findings of three patients affected by progressive supranuclear palsy (PSP) are reported. The radiological picture consisted of atrophy of the midbrain and quadrigeminal plate, with prominent interpeduncular, crural, ambient, and quadrigeminal plate cisterns, and dilatation of the aqueduct and third ventricle. These features were not related to the duration of the illness and degree of neurological deficits. In the authors' opinion CT is useful in the differential diagnosis of PSP and other extrapyramidal disorders.
