Abstract
Cerebellar mutism syndrome (CMS) was first described by Rekate et al in 1985. This syndrome is a
common complication of posterior fossa surgery in children with range of 11-29% and usually manifests as
diminished speech, hypotonia, and ataxia. The cause is due to bilateral pertubation of the dentate nuclei
and their efferent pathways by edema, perfusional defects, axonal damage or metabolic disturbances.
Other rare causes of CMS like acute subdural hematoma of the posterior fossa, head injury, brainstem
glioma surgery, meningitis and basilar artery occlusion have also been reported. CMS after supracerebellar
resection of the pineal tumor is a very rare with very few cases reported. We report such a case in a 10-
year old boy who underwent excision of a pineal tumor through the infratentorial supracerebellar route.
