Cerebellar mutism is a rare postoperative complication of posterior fossa surgery in the pediatric age group and is classically transient, with cranial nerve dysfunction and long-tract signs. It consists of diminished speech progressing to mutism, emotional lability, hypotonia, and ataxia. Although the pathophysiology and anatomical substrate of cerebellar mutism still remain unclear, the most accepted cause for this condition is vascular spasm with involvement of the dentate nucleus and the dentatorubrothalamic tracts to the brain-stem, and subsequently to the cortex. This disorder has been described in many other situations and consequently neurosurgeons should be familiar with its symptoms, physiopathology, diagnosis, degrees of severity, treatment, and prognosis, since a multidisciplinary approach is required. We therefore made an attempt in this paper to further understand this entity using the relevant literature.
