Doctors Who Treat Arachnoid Cysts

A child or young adult diagnosed with an arachnoid cyst should be evaluated by a pediatric neurosurgeon with advanced training and extensive experience in treating these cysts in children. The combined pediatric neurosurgery service at Weill Cornell Medicine Neurological Surgery and Columbia University offers the services of four of the top pediatric neurosurgeons in the field:

Mark Souweidane, MD, is vice chair of Weill Cornell Medicine Neurological Surgery and director of Weill Cornell Medicine Pediatric Neurosurgery, is internationally recognized as an expert in the field of pediatric neurosurgery, including arachnoid cysts. He has been named one of America’s Top Doctors by Castle Connolly, and is regularly included on lists of the nation’s Best Doctors and Super Doctors. A pioneering champion of minimal access neurosurgery, Dr. Souweidane has specialized endoscopic surgical skills that attract patients and practitioners that benefit from his talents.

Neil Feldstein, MD, has expertise in the full range of pediatric neurosurgical conditions, with special interest in arachnoid cysts, Chiari malformations, spinal dysraphism, brain and spinal cord tumors, craniofacial abnormalities, and neurovascular conditions. (Read more about Dr. Feldstein.)

Jeffrey Greenfield, MD, PhD is Professor of Neurological Surgery in Pediatrics at Weill Cornell Medical College and a pediatric neurosurgeon at NewYork-Presbyterian Hospital and Weill Cornell Medicine. Dr. Greenfield, whose laboratory research includes the Children’s Brain Tumor Project, specializes in minimally invasive (endoscopic) pediatric neurosurgery as well as in advanced surgery for other pediatric conditions of the brain and spine.

Caitlin Hoffman, MD, is a board-certified neurosurgeon who specializes in pediatric neurosurgery as well as in adult and pediatric epilepsy surgery. She has completed fellowship training in pediatric neurosurgery and has performed extensive research on the molecular mechanisms of progression of brain tumors, specifically medulloblastoma. Dr. Hoffman’s clinical research includes venous anomalies in craniosynostosis, early surgical treatment for Rasmussen’s encephalitis, minimally invasive methods of treating hydrocephalus and intracranial cysts, and the characteristics and safety of invasive monitoring for pediatric neurovascular disorders such as AVM.
