Résumé :

Central pontine and extra-pontine myelinolysis (CPM/EPM) is a rare neurological disorder, well documented for more than 50 years but whose pathogenesis remains obscure. The existence of predisposing factors occurs in the most cases ; chronic alcohol abuse is one of the most commonly encountered, among many others. Alcohol withdrawal represents an additional vulnerability factor, being responsible for electrolyte imbalances which are not always demonstrable but are certainly involved in the development of CPM and/or EPM. CPM/EPM may be responsible for severe morbidity and is potentially life-threatening. The diagnosis of CPM/ EPM remains mostly clinical and is confirmed by magnetic resonance imaging of the brain. It should be considered in the setting of any unexplained neurological symptoms during the course of alcohol withdrawal or for any patient with chronic alcohol abuse, as promptly as possible, given the potentially fatal outcome.
