  • Clinical Assistant Professor

Chikezie Eseonu, MD, is a clinical assistant professor at UPMC Pinnacle. He received his undergraduate degree at Harvard University in biomedical engineering in 2007 and completed his medical education at Yale School of Medicine in 2011. 

Following medical school, Dr. Eseonu completed his neurosurgery residency at Johns Hopkins Hospital in Baltimore, Md., where he also completed an enfolded neuro-oncology/endoscopic/skull base fellowship.

Dr. Eseonu's clinical interests embrace several aspects of brain tumor treatment, including open surgical, minimally invasive or radiosurgical techniques. He is also involved in the treatment of trigeminal neuralgia, Chiari malformation, hydrocephalus, and other general neurosurgical conditions including degenerative spine, spinal stenosis, disc herniation, trauma and carpal tunnel.

Dr. Eseonu's research has encompassed such areas as surgical technique and outcome studies for gliomas, pituitary adenomas, trigeminal neuralgia, and awake craniotomy for brain tumors, as well as cost efficacy studies in neurosurgery. He has published over 30 peer reviewed papers and book chapters.

He is licensed to practice in Pennsylvania and is a member of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons.
