Cerebellar Mutism after posterior fossa tumor surgery: is it predictable, preventable, treatable?

Introduction: Posterior fossa tumors pose challenges in pediatric neurosurgery and can lead to complications such as cerebellar mutism, affecting speech and motor abilities.

Descrição
Resumo:Introduction: Posterior fossa tumors pose challenges in pediatric neurosurgery and can lead to complications such as cerebellar mutism, affecting speech and motor abilities. This study aims to describe the evolution of cerebellar mutism and identify relevant factors in its pathophysiology and prognosis. Methods: A review was conducted on three cases of children who underwent surgery for posterior fossa tumors by the same surgical team and developed postoperative cerebellar mutism. The study analyzed preoperative clinical presentation, mutism manifestation, and recovery. Additionally, a literature review was performed on the emergence, evolution, and prognosis. Results: Case 1 involved a 3-year-old girl with medulloblastoma who experienced mutism, behavioral changes, and self-mutilation after surgery. Symptoms resolved after one month but recurred with a subsequent operation, resolving again after a month. Case 2 featured a 15-year-old girl who developed severe posterior fossa syndrome, including mutism, dysarthria, aphasia, and motor impairments. With support care, she gradually improved over a year. Case 3 involved a 4-year-old boy with cerebral palsy and a posterior fossa tumor. He experienced akinetic mutism, resolved over time with rehabilitation therapies. Discussion: Cerebellar mutism following posterior fossa surgery has implications for patient recovery. It primarily involves impairment of cerebellar outflow pathways rather than direct brainstem or cortical lesions. Identifying at-risk patients remains challenging, though younger age and specific tumor characteristics may increase the likelihood of mutism. Rehabilitation, including physical and speech therapies, plays a crucial role in promoting recovery. Effective communication and support for patients and their families are essential during the recovery process.
