Putaminal Diffusion Restriction in a Case of Methanol Toxicity with Clinical Recovery

A 32-year-old male presented to the emergency department for confusion, dyspnea, and a "white out" of his central vision over the preceding 24 hours. The patient had recently consumed a bottle of alcohol purchased overseas. Bloodwork revealed a severe metabolic acidosis (pH 6.90) and a critically high methanol level of 28.9 mmol/l. Shortly after presentation, the patient went into respiratory failure and became comatose. He was intubated and admitted to the ICU.
