A range of pituitary tumor-related conditions all benefit from a multidisciplinary approach
Although usually noncancerous, pituitary tumors are complex disorders and can produce multifaceted effects that manifest throughout the body. For this reason, their optimal management often requires a multidisciplinary approach.

“For the most favorable outcomes, it’s important that patients with pituitary tumors be treated at a dedicated pituitary center with various specialists who have expertise in dealing with these rare conditions,” says neuroendocrinologist Divya Yogi-Morren, MD, Medical Director of Cleveland Clinic’s Pituitary Center.
In the latest episode of Cleveland Clinic’s Neuro Pathways podcast, Dr. Yogi-Morren joins neurosurgeon Pablo Recinos, MD, Section Head of Skull Base Surgery at Cleveland Clinic, to explore the essentials of managing pituitary tumors and other pituitary disorders. They jointly cover the following:

Podcast host Glen Stevens, DO, PhD: Tell us about the diagnostic workup for a patient with a suspected pituitary tumor.
Divya Yogi-Morren, MD: We of course use evidence-based guidelines from the major endocrine societies to standardize our diagnostic approaches and inform our treatment decisions. Basically, we begin with the hormone evaluation, which I've already spoken about. We also have to do dynamic testing for pituitary tumors — sometimes to evaluate pituitary reserve, but also to evaluate the behavior of the tumor and how the tumor is producing its hormones. That's critical from the endocrine standpoint.

We also use MRI, which is the gold standard for visualizing pituitary tumors. Sometimes we also have to do something called inferior petrosal sinus sampling. This involves sampling blood from the inferior petrosal sinuses that drain the pituitary and then measuring hormone levels there. We enlist our neurointerventional radiologist colleagues to perform that procedure.
When it comes to monitoring, we also need to do visual field testing with our neuro-ophthalmologist. So we definitely need a variety of tools and specialists in order to diagnose these conditions correctly before patients can undergo surgery or radiation or any other intervention.
Glen Stevens, DO, PhD: I imagine that some providers out there may just order an MRI. But you have a very specific protocol where you do a pituitary-specific MRI and obtain the important sequences in that area, correct?
Pablo Recinos, MD: Absolutely. And it actually depends on whether we're looking from a diagnostic perspective or from a surgical perspective. In the latter context, we use MRI to provide GPS-like image guidance to inform the surgery.
