Introduction. Pilocytic astrocytoma and cerebellar medulloblastoma are the most common pediatric brain tumors. After the removal of tumors, complications may occur: damage to cranial nerves and corticospinal tracts, cerebellar ataxia, motor disorders, neurovegetative and cognitive changes, cerebellar mutism. These clinical manifestations are very diverse and with different degrees of expression depending on the anatomical location of the lesions and the involvement of distributed neural circuits. The purpose of the work. Evaluation of associated neurological manifestations in children with operated cerebellar tumors. Methods. 36 children who underwent total resection of the cerebellar tumor, operated between 2001 and 2022, were examined, including 6 children with medulloblastoma and 30 with pilocytic astrocytoma. Patients were examined in the late postoperative period in the years 2017-2022. The clinical method, vegetative evoked potentials, electroencephalography, neurocognitive and neuropsychological tests were used. The obtained data were statistically processed through the Quanto program. Results. Postoperative cerebellar mutism syndrome was present in 61% of patients (6 with medulloblastoma, 16 with pilocytic astrocytoma). Persistent dysarthria at least 2 years after the intervention was established in all patients with medulloblastoma and 15 children (93.85%) with pilocytic astrocytoma and postoperative cerebellar mutism. Cerebellar cognitive affective syndrome defined - in 100% of those with medulloblastoma, 90% of those with pilocytic astrocytoma. Conclusions. Speech and language disorders lead to academic failure and loss of friendships, with devastating negative effects on healthy development and socialization, longterm quality of life in children operated on with cerebellar tumors.
