Cerebellar mutism is an uncommon complication of posterior fossa surgery.
Manifestations include disturbances of articulation, prosody, and pitch,
and, if severe, complete mutism.
Symptoms are independent of recognizable
cortical or brainstem injury, and recovery is variable, with permanent
deficits frequently observed. Cerebellar dysfunction is commonly invoked as
an etiology, although controversy remains concerning the mechanism.
Visual
impairment has been reported only once before in the setting of this
disorder.
We report a confirmatory case of sudden, severe visual loss in
association with cerebellar mutism after resection of a midline
medulloblastoma in a 7-year-old.
