title: Ethylene glycol poisoning: diagnosis based on high osmolal and anion gaps and crystalluria.
abstract: We report a case of ethylene glycol poisoning in a 54-year-old man found comatose on the street. No history was available. The diagnosis was based on the findings of a high anion gap metabolic acidosis, a high osmolal gap, and the presence of oxalate and hippurate crystals in the urine. The diagnosis was confirmed later by an ethylene glycol level of 775 mg/dl. This case illustrates how these parameters can be used in the emergency department for rapid diagnosis and management.
