Ethylene glycol intoxications are quite rare. The toxicity of ethylene glycol is largely related to its metabolites rather than the parent compound itself. Our case report represents the typi­cal clinical findings (neurological, cardiopulmonary and renal phase) and laboratory results (elevated serum osmolality, high osmolal gap, high anion gap metabolic acidosis, calcium oxa­late crystals in the urine) of an ethylene glycol intoxication. Given the potentially high morbi­dity and mortality of this intoxication, its quick recognition is essential. Treatment includes securing the patient’s airway, breathing and circulation, administering bicarbonate and an antidote (ethanol, fomepizole), hemodialysis, and sometimes also the administration of cofac­tors of ethylene glycol metabolism (thiamine, pyridoxine, and magnesium).
