Tomographic diagnosis of pituitary microadenomas in Forbes-Albright syndrome (amenorrhea-galactorrhea).

The present study documents a characteristic tomographic sellar abnormality in five patients with Forbes-Albright syndrome (ammenorrhea-galactorrhea) and surgically proved pituitary microadenomas. This abnormality, noted in patients with normal-sized sellae, consists of asymmetric erosion of the anterior inferior wall of the sella turcica. Utilizing the twin criteria of an elevated serum prolactin and characteristic sella abnormality, herein described, previously unrecognized patients with pituitary microadenomas can be diagnosed and treated effectively.
