Cerebellar Mutism Treated Successfully With Zolpidem in a Patient With Learning Difficulties
1Surgery, King Abdulaziz University, Jeddah, SAU.
Abstract:
Posterior fossa tumors constitute the most common brain tumor in pediatrics with 25% development postresection. Cerebellar mutism can manifest as neurobehavioral abnormalities that can occur within days to months after surgery but usually peak on the third postoperative day. It can be caused by discontinuation of dento-thalamo-cortical pathway in the vermian lesion, due to edema, tumors, and hypoperfusion. We report a seven-year-old patient with posterior fossa lesion (pilocytic astrocytoma in histopathology) and learning difficulties with symptoms of urinary retention, pseudobulbar palsy, and motor incoordination that were treated successfully with zolpidem 2.5 mg with regain of function by the third month.
