Cerebellar mutism syndrome (CMS) is a common complication of posterior fossa surgery that can confound the postanesthetic examination and have long-lasting impacts. There is confusion surrounding its precise description, diagnostic features, and associated morbidity. Here, we discuss the most up-to-date knowledge of CMS drawing from a clinical case in the context of 3 new reports: (1) an international consensus paper presenting a new proposed working definition by the Iceland Delphi Group, (2) a knowledge update by Gadgil et al, (3) and a review of neuroimaging-based data elucidating the etiology of CMS by Patay.
