Vitamin E deficiency ataxia associated with adenoma.

Vitamin E is one of the most important lipid-soluble antioxidant nutrient. Severe vitamin E deficiency (VED) can have a profound effect on the central nervous system. VED causes ataxia and peripheral neuropathy that resembles Friedreich's ataxia. We report here a patient presenting this syndrome, but also a prolactin and FSH adenoma. Both the neurological syndromes and the adenoma regressed after treatment with alpha-tocopherol. Although, the presence of the prolactinoma in this patient may not be related to his vitamin E deficiency, alpha-tocopherol treatment seems to be beneficial and might usefully be tested in patients with hypophyseal secreting other forms of adenoma.
