AB058. Giant bilateral intraventricle ependymoma in pediatric patient with essential tremor as a main symptom: a rare case report.

Background: Giant bilateral intraventricle ependymoma in pediatric patient is indeed a rare type of brain tumor that primarily affects children, accounting for about 5-10% of all brain tumors in children. It arises from ependymal cells, which line the ventricles of the brain and the spinal cord. Essential tremors in the tumor brain have been related to several brain areas, including the thalamus, cortex, globus pallidus, and cerebellum.

Case description: We presented an 8-year-old boy with diagnosed ependymoma with essential tremor, double vision, and dyspnea as symptoms. The magnetic resonance imaging (MRI) with contrast showed the mass appears to be isointense with clear boundaries and regular edges; the impression comes from the bilateral ventricle lateral, which is welded to the bilateral thalamus. A surgical resection was performed in this case. The indication for surgery in this case was due to symptoms of shortness of breath and tremors that unstopped since 1 month ago. The surgery was performed with bilateral occipital craniectomies with the aim of facilitating access to the tumor and a bilateral occipital transcortical approach. Histopathological examination revealed support for an ependymoma.

Conclusions: Ependymoma, especially in children, has various symptoms based on the size, location, and extent of the tumor. MRI with contrast is the main modality for the diagnosis of ependymomas, followed by histopathological examination to confirm. Ependymoma should be considered, and these tumors must be monitored routinely because they can recur. It should be conducted in a multidisciplinary manner to ensure excellent outcomes and avoid fatal complications.
