PURPOSE: 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. METHODS: This paper is a synopsis of the first global meeting, a 3-day program held in Liverpool, England, UK, in September 2022. RESULTS: 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. CONCLUSIONS: 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.
