[Neurosurgery and pituitary tumors: from preoperative tests to postoperative follow-up]

Accurate diagnosis of a pituitary tumor requires coordinated medical collaboration. Guidance learned from experience is essential for MRI exploration of pituitary tumors, especially microadenomas. Therapeutic strategy depends largely on the accurate examination of the radiological data that guides the surgical approach and determines, for the patient and family, the possibility of tumor and/or endocrinological cure.

Secreting tumors are diagnosed by assessment of hypophyseal function, predictive of medical treatment efficacy and the value of hormone replacement therapy in case of surgery.
