Mutism after cerebellar medulloblastoma surgery

Area of Science:

• Pediatric Neurology
• Neuro-oncology
• Speech Pathology

Background:

• Medulloblastoma is a common pediatric brain tumor.
• Surgical resection is a primary treatment modality.
• Post-operative neurological deficits can occur.

Observation:

• A 9-year-old boy presented with transient mutism after surgical removal of a medulloblastoma in the cerebellar vermis region.
• The patient did not exhibit reduced consciousness or disturbances in caudal cranial nerves or phonation.
• The mutism resolved spontaneously within a 6-month period post-surgery.

Findings:

• The case highlights transient mutism as a potential, albeit uncommon, post-operative complication following cerebellar vermis medulloblastoma resection.
• The absence of other neurological deficits suggests a localized impact on speech pathways.
• Phenomenology, pathogenesis, and etiology of this specific neurological presentation were analyzed.

Implications:

• Understanding rare neurological sequelae like transient mutism is crucial for comprehensive post-operative care in pediatric neuro-oncology.
• Further investigation into the precise mechanisms underlying speech disturbances after cerebellar surgery may refine treatment strategies.
• This case contributes to the literature on rare neurological deficits following brain tumor resection in children.
