Résumé : The authors report the case of a 54-year old type-2 diabetic female patient with a Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). She progressively developed distal hypoesthesia and tetraparesis. She deteriorated after two courses of intravenous immunoglobulins (IVIG) administration and became rapidly wheelchair bound. After one month of steroid treatment, the patient was walking alone. This case raises the question whether IVIG is to be considered as first line treatment for diabetes associated CIDP.
