Hyperprolactinemia as a manifestation of multiple sclerosis attack.

Background: Multiple Sclerosis is a chronic inflamatory disorder. The prevalence of hyperprolactinemia in patient with MS is 6.7 %. Method: Case report. Result: This case report describes a 31-year-old woman with multiple sclerosis (MS) who presented with galactorrhea, a rare symptom of MS, along with other neurological manifestations. She had elevated serum prolactin levels and a normal-sized pituitary gland with no evidence of adenoma or lesions. The elevated serum prolactin levels were normalized after treatment with intravenous methylprednisolone. No dopaminergic drugs were used to treat her galactorrhea, which also resolved after receiving intravenous methylprednisolone. Conclusion: This case illustrates the possible association between MS and hyperprolactinaemia and if the etiology is MS there is no need for treatment of hyperprolactinemia.
