Abstract
Objective. – To describe an electroclinical presentation of a peripheral neuropathy in a patient who suffered from vitamin B12 deficiency. Patient and methods. – We report the case of a 56-year-old man who, 17 years after a subtotal gastrectomy, presented with a diffuse sensory-motor demyelinating peripheral neuropathy with multifocal alteration of conduction confirmed by electromyography. Its causal relationship with vitamin B12 deficiency was biologically demonstrated. This neuropathy improved within a few days after intramuscular hydroxocobalamin treatment. Both clinical and electrophysiological signs had totally disappeared 3 months later on. Conclusion. – This observation demonstrates that, in spite of its poor outcome reported by several authors, peripheral neuropathy induced by vitamin B12 deficiency can recover completely with substitutive treatment.
