title: Primary intrasellar germinoma in a woman presenting with secondary amenorrhea and hyperprolactinemia.
abstract: A 32-year-old woman with secondary amenorrhea was found to have an elevated level of serum prolactin, partial diabetes insipidus, and a subtle visual field defect. A primary intrasellar tumor was noted on the computed tomographic scan. Although the tumor had some characteristics of a prolactinoma, transsphenoidal exploration revealed a primary germinoma. The tissue diagnosis led to appropriate treatment with radiotherapy. The tumor regressed, and the patient had a spontaneous pregnancy. Had dopamine agonists been used initially, amelioration of the hyperprolactinemia and delay in the proper diagnosis and treatment would have occurred.
