Abstract

When there is clinical suspicion of a pituitary tumor, localization of the tumor and representation of the relation of the tumor to adjacent structures by imaging are prerequisite in establishing the indication for surgery and in planning the operative strategy. Usually, large pituitary tumors do not give rise to problems in CT diagnosis, especially since they will already have led to dilatation of the sella at this stage and will have extended to the suprasellar region (12, 15). However, very tiny hormone-producing tumors (ACTH- and GH-producing adenomas, prolactinomas) in the stage of microadenomas, tumor relapses, and tumor remnants cannot always be localized unequivocally in the adeno-hypophysis or in the former area of operation (3, 5, 6, 8, 11, 17).
