Advanced diagnosis and treatment. In Cushing's syndrome, small pituitary tumors that lead to an excess release of adrenocorticotropic hormone (ACTH) are often too small for detection by traditional magnetic resonance imaging (MRI). Mayo Clinic's high-field, 3-tesla (3-T) MRI provides better viewing of these tumors.
Mayo Clinic's neuroradiologists are experienced in performing inferior petrosal sinus sampling to help find and identify tumors. This test involves obtaining a sample from these sinuses, where the pituitary gland drains hormones into the bloodstream, including ACTH.
Mayo Clinic was among the first institutions to extensively research an endoscopic through-the-nose (transnasal) surgical tumor removal technique that has now become standard practice. This method is highly successful, reduces discomfort and usually requires only an overnight stay in the hospital.

Its surgeons have experience and expertise in endoscopic transsphenoidal surgery and in using stereotactic radiosurgery, fractionated radiation therapy or proton beam radiation to treat these tumors.
