Methanol intoxication: distribution in postmortem tissues and fluids including vitreous humor

Area of Science:

• Toxicology
• Emergency Medicine
• Forensic Pathology

Background:

• Methanol poisoning is a life-threatening condition that can lead to severe metabolic disturbances and organ damage.
• Early recognition and prompt treatment are crucial for patient survival.

Observation:

• A 44-year-old male presented in a coma with severe metabolic acidosis, high anion gap, and high osmolal gap.
• Initial laboratory results revealed a critically high serum methanol concentration (583 mg/dL).
• Other toxic alcohols like ethanol and ethylene glycol were ruled out.

Findings:

• Despite immediate treatment with ethanol, bicarbonate, and hemodialysis, the patient demised 40 hours after admission.
• Postmortem toxicological analysis detected significant methanol concentrations in various body fluids (bile, vitreous humor, blood) and tissues (brain, kidney, lung, liver, etc.).
• Gas chromatography with flame ionization detection was utilized for accurate methanol quantification.

Implications:

• This case underscores the extreme toxicity of methanol and the challenges in managing severe poisoning.
• Accurate postmortem analysis is vital for confirming methanol as the cause of death and for understanding its distribution in the body.
• Highlights the importance of public awareness regarding the dangers of ingesting methanol.
