TO THE EDITOR: In Cushing syndrome, selective pretrosal sinus sampling has been shown to be useful in localizing adrenocorticotrophic hormone (ACTH) secretion to the pituitary gland when other studies have been inconclusive (1). Bilateral sampling increases sensitivity and has also been shown to be reliable in lateralizing the lesion (1-5). In a few cases in which a focal lesion was not identified at surgery, a cure has been effected by hemihypophysectomy, with the correct side being selected based on petrosal sinus sampling data ( 1 ). We report a case of false lateralization of a pituitary microadenoma by bilateral inferior
