Cerebellar infarction--clinical and computed tomographic correlations.

Fifteen patients with CT evidence of cerebellar infarction were analyzed. In 10 patients, there were premonitory symptoms. In all cases, development to maximal neurological deficit occurred within 4 hr. All patients presented with gait disorder, and they had cerebellar abnormalities on examination. Eight of the 15 had accompanying findings consistent with brain stem dysfunction. CT showed a hypodense lesion which was either wedge, rectangular or ovoid shaped. Only 3 had evidence of fourth ventricular compression with accompanying third and lateral ventricular enlargement. No patient required surgery and all patients survived with good functional recovery.
