Pituitary adenomas: current methods of diagnosis and treatment

Pituitary adenomas are benign neoplasms that can be effectively managed by a variety of therapeutic options. The clinician's goal in managing patients with these tumors should be to minimize the morbidity of each intervention used in diagnosis and treatment. Standard diagnostic interventions include MRI, hormonal assessment, and tissue diagnosis. Therapies include transsphenoidal surgery, external-beam radiotherapy, newer stereotactic irradiation techniques, and medical management. Appropriate treatment selection requires detailed knowledge of the expected outcomes and side effects of each option. Newer and perhaps less toxic treatment techniques are evolving and require further evaluation.
