LYMPHOCYTIC HYPOPHYSITIS - A RARE CAUSE OF HYPERPROLACTINEMIA

Lymphocytic hypophysitis is one of the rare causes of hypopituitarism and intrasellar mass observed almost exclusively in women. A temporal relationship to pregnancy has been identified in many but not all of t he 34 reported cases. Intra-operative differentiation from non-secreto ry macroadenoma is important, as resection of the anterior lobe is unn ecessary in these individuals and pituitary function may spontaneously return to normal. The authors present the case of a woman with sympto matic hyperprolactinaemia 10 years after her last pregnancy.
