From time to time on the Neurosurgery Blog, you will see us cross-posting or linking to items from other places when we believe they hit the mark on an issue. We wanted to bring attention to a recent online-only supplement in Neurosurgery, “Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines for Patients With Functioning Pituitary Adenomas.” Neurosurgery is the official journal of the Congress of Neurological Surgeons, which provides multimedia, prompt publication of scientific articles on clinical or experimental surgery topics important for the brain, spine, and peripheral nerves, reviews, and other information of interest to readers across the world.
Published August 15, 2025, the supplement provides comprehensive, evidence-based guidelines on the care of adults with functioning pituitary adenomas (FPA). Tailored for neurosurgeons, endocrinologists, and other specialists, the guidelines mark a pivotal step in standardizing care, optimizing patient outcomes, and promoting multidisciplinary coordination.
The CNS and the American Association of Neurological Surgeons (AANS) have endorsed the guidelines. The initiative was led by Isabelle M. Germano, MD, MBA, Professor of Neurosurgery at the Icahn School of Medicine at Mount Sinai and Chair of the AANS/CNS Section on Tumors (2022–2024), along with D. Ryan Ormond, MD, PhD, Associate Professor of Neurosurgery at the University of Colorado School of Medicine. Together, they assembled and worked with a multidisciplinary team of 18 experts in neurosurgery, endocrinology, neuroradiology, and radiation oncology from across the country to develop these guidelines.

From his early days in Buffalo, New York, to the hallowed halls of the Cleveland Clinic, Don’s story is the stuff of legend. After earning his medical degree from the University of Buffalo, he trained under giants like Dr. Walter Hamby and Dr. W. James Gardner, Jr., becoming a force of nature in his own right. He didn’t just train neurosurgeons — he built neurosurgical training. Over 45 neurosurgeons and fellows passed through his tutelage as he helped formalize the educational structure of neurosurgical residency, moving it beyond the traditional apprenticeship model.
Chris was born Dec 22, 1961, in Milton, MA. His family had a legacy of several generations attending the prominent Milton Academy, and Chris followed in those footsteps, as he was often proud to point out. He attended Princeton University, followed by medical school at Tufts. His career was shaped by his neurosurgical training at Thomas Jefferson University, where he developed a passion for cerebrovascular surgery under the guidance of Dr. William Buchheit. He then pursued a fellowship in Pittsburgh under Drs. Peter Janetta, Dade Lundsford, and Douglas Kondziolka, where he honed his microvascular and radiosurgery skills.

To achieve this goal, Dr. Pilitsis worked toward gaining experience in the clinical, educational and research aspects of medicine at Albany Medical College. After a national search, she became the chair of The Department of Neuroscience and Experimental Therapeutics. Subsequently, she obtained additional leadership training through the Harvard course for chairs, Executive Leadership in Academic Medicine and earned a Masters in Business Administration. To help garner institutional budget experience, she joined the system’s finance committee. To gain philanthropy experience, she obtained formal training and worked closely with her institutional foundation.
In 2022, Dr. Pilitsis became the dean and vice president of medical affairs at Schmidt College of Medicine at Florida Atlantic University (FAU). She is the first female neurosurgeon to become a medical school dean. “A community is essential for all of us to get to where we are going. The central tenet of my time at FAU will echo that spirit of developing a health care workforce ‘of the community, for the community.’ I am proud to be a part of the neurosurgical community,” states Dr. Pilitsis.
However, when I saw the magic of focused ultrasound showing immediate relief of tremors following a real-time thalamotomy under magnetic resonance imaging guidance, I knew the field would never be the same. I then embraced this new technology, as Dr. Grady would have insisted. I was privileged to continue to lead this program at Stanford during my time there and work with terrific colleagues such as Pejman Ghanouni, MD, PhD; Jaimie M. Henderson, MD, FAANS; Kim Butts-Pauly, PhD and an international team of experts to get this treatment FDA-approved.
Deep brain stimulation remains commonplace in my practice, but offering treatment options is key to program-building and patient care. I liken this optionality to brain aneurysm management. There was a time when neurosurgery could have lost control of this space due to interventional radiology’s offering of incisionless coil procedures. However, the sub-specialty of endovascular neurosurgery was created, and our necessary role in both the angiography suite and operating room was solidified. Stereotactic and functional neurosurgeons must embrace ablation techniques using focused ultrasound in much the same way. Patients want options, and finally they have them.
