A case of a parasellar cavernous hemangioma, which manifested a galactorrhea-amenorrhea syndrome without abnormal neurological findings is reported.
A 41-year-old female was admitted showing galactorrhea and amenorrhea for three months. The endocrinological tests were almost normal except for hyperprolactinemia. A plain skull X-ray revealed a double floor of the sella turcica. A computerized tomography scan revealed an isodensity area which was enhanced slightly with a contrast medium in the parasellar region of the right middle fossa. The angiograms showed an avascular mass lesion from the sella turcica to the right middle fossa. The sinograms of cavernous sinus clearly demonstrated an indentation in the right cavernous sinus. A pituitary adenoma with lateral extension was suspected. The tumor was subtotally removed and was histologically diagnosed as a cavernous hemangioma. The postoperative course was uneventful. The galactorrhea and amenorrhea ceased in one month postoperatively and the prolactin level in the serum became normal forty days after the operation.
Cases similar to this have never been previously reported. The possible cause of the hyperprolactinemia of this case is discussed.
