| Abstract: | The empty sella turcica may be found in people with no antecedent history of intracranial disease, as well as in those with known pituitary pathology or following therapy to the pituitary gland. We have evaluated 3 women with galactorrhea and hyperprolactinemia, 2 of whom had amenorrhea. Each had an empty sella. In all cases polytomograms demonstrated asymmetry of the sella floor with focal bony erosion, conventional pneumoencephalography showed intrasellar air, and polytomographic pneumoencephalography confirmed air limited to one side of the pituitary fossa with tumor and/or residual normal tissue on the opposite side. In 2 patients who had extensive endocrine evaluation, pituitary function was normal with the exception of hyperprolactinemia. Transsphenoidal excision of microadenomas resulted in postoperative normalization of the serum prolactin concentration and resumption of regular menses in the previously amenorrheic women. |
