MyChart
The St. Luke's Pituitary Program team specializes in the evaluation and treatment of pituitary disorders. Our multidisciplinary approach brings together pituitary experts from neurosurgery, endocrinology, and otolaryngology (ear, nose and throat) to recommend the latest medical and surgical treatments tailored to each patient’s individual needs. We focus on optimal management of challenging pituitary disorders, including those best treated with medications, and have extensive experience in modern, minimally invasive endoscopic surgery techniques to remove even large and complex pituitary tumors (typically through the nose). We also offer a full range of specialized, diagnostic studies including neuro-ophthalmological testing and dynamic MRI imaging.
Your best outcome is our highest priority, so you can expect close connections between your surgical team, your endocrinologist, and your primary care provider. We also work closely with St. Luke's Cancer Institute and participate in a Central Nervous System Tumor Board attended by a multidisciplinary team including experts in medical oncology, radiation oncology, neuroradiology, pathology, genetics, and physical therapy/neurologic rehabilitation. Together, we discuss strategies to ensure your best outcome and a successful recovery.
The St. Luke's pituitary program evaluates patients through a streamlined process that includes an initial neurosurgery consultation and outpatient evaluation by endocrinology and otolaryngology experts. Symptoms of a pituitary issue can include vision loss when a pituitary tumor puts pressure on the optic nerve. If you experience vision loss, please consult with your primary care provider for a referral.
