Benign pituitary adenoma associated with hyperostosis of the spenoid bone and monocular blindness. Case report.

The authors describe a case of benign chromophobe adenoma associated with hyperostosis of the lesser wing of the sphenoid bone and monocular blindness in a 38-year-old woman. The endocrinological and radiological evaluations were all suggestive of a meningioma. The diagnosis was established by biopsy of the tumor mass. After orbital decompression and removal of the tumor, the patient was treated with radiation therapy. Her postoperative course was uneventful, and her visual defects remained fixed.
