Endoscopic Resection of Pilocytic Astrocytoma of the Third Ventricle: A Case Report

Abstract

Pilocytic astrocytoma of the third ventricle is a very rare localization. It occurs mainly during the first two decades of life. The tumor is most often revealed by an HTIC syndrome. Brain imaging allows to establishment of a diagnostic hypothesis, which is confirmed only after an anatomopathological study.  We report the case of a six-year-old child with an astrocytoma of the third ventricle. He was admitted with intracranial hypertension. Agross total resection was performed using tans-frontal trans-ventricular endoscopy. Histological examination confirmed the diagnosis of pilocytic astrocytoma. Postoperative follow-up was straightforward, and the child made a full recovery. To our knowledge, only a few reports of intraventricular pilocytic astrocytomas have been published and none have described endoscopic resection in the pediatric population which can be a good alternative option in this case.
