Objective: To present a case of survival without visual and central nervous system sequelae at a formate concentration of twice the reported lethal level. Clinical Presentation and Intervention: This was a case of a 33-year-old man who ingested 1 liter of a toxic mixture of methanol and ethanol.

Upon admission, he presented with anxiety, tachycardia and hypertension and had a serum formate level of 1,400 mg/l (normal range 0.9-2.1 mg/l), a methanol level of 806 mg/l (normal range 2-30 mg/l), an undetectable ethanol concentration and a normal lactate level. A 10% solution of ethanol and folinic acid was administered intravenously and two 8-hour sessions of intermittent hemodialysis were performed.

The patient was discharged on the fifth day without sequelae of poisoning. The follow-up examinations 3 months and 2 years later revealed no damage to the basal ganglia.

The patient had normal visual-evoked potential and findings on optical coherence tomography. The genetic analysis revealed a rare minor allele for the gene coding CYP2E1 enzyme of the microsomal ethanol oxidizing system.

Conclusion: The patient survived acute methanol poisoning without long-term sequelae despite a high serum level of formic acid upon admission. (C) 2015 S. Karger AG, Basel
