Parkinsonian syndrome after methanol intoxication.

This is a report of a case of acute methanol intoxication (AMI) with an exceptional central nervous system (CNS) damage producing a parkinsonian syndrome. This symptomatology persisted as a sequel. Computed axial tomography (CAT) scan showed areas of decreased attenuation at lenticulocapsular regions. The authors remark on the correlation of these CAT scan abnormalities and the pathological findings in necropsy studies described in the literature. They think that these lesions are produced by severe methanol intoxications, generally with a fatal outcome. They suggest the CAT scan diagnostic utility in patients with metabolic acidosis and coma of unknown etiology.
