Abstract

LIZARAZO, Jairo  and  NOVOA, María Alexandra. Anterograde amnesia due to bilateral lesion of the hippocampus in a patient probably intoxicated with metanol. Acta Neurol Colomb. [online]. 2018, vol.34, n.2, pp.132-138. ISSN 0120-8748.  https://doi.org/10.22379/24224022202.

We report the case of a 56-year-old man who was hospitalized because acute altered consciousness after alcoholic intoxication. During his hospitalization, there was observed an alteration of anterograde memory and right optic neuropathy. Diagnostic images showed bilateral lesions of the hippocampus, globus pallidus and paramedian cerebral frontal cortex. The neuropsychological evaluation confirmed a severe anterograde amnesia that barely improved after 2 years of follow up. Despite the lack of confirmation by the laboratory, the clinical manifestations and imaging results are in favor of methanol intoxication. Attention is drawn to this rare clinical presentation.
