Proceedings of the first global meeting of the Posterior Fossa Society: state of the art in cerebellar mutism syndrome

The Posterior Fossa Society, an international multidisciplinary group, hosted its first global meeting designed to share the current state of the evidence across the multidisciplinary elements of pediatric post-operative cerebellar mutism syndrome (pCMS). The agenda included keynote talks from world-leading speakers, compelling abstract presentations and engaging discussions led by members of the PFS special interest groups. This paper is a synopsis of the first global meeting, a 3-day program held in Liverpool, England, UK, in September 2022. Topics included nosology, patient and family experience, cerebellar modulation of cognition, and cerebellar cognitive affective syndrome. In addition, updates from large-scale studies were shared as well as abstracts across neuroradiology, neurosurgery, diagnosis/scoring, ataxia, and rehabilitation. Based on data-driven evidence and discussions, each special interest group created research priorities to target before the second global meeting, in the spring of 2024.
