Intraventricular Pilocytic Astrocytoma: A Case Report

Background: Pilocytic astrocytoma (PA) is a low-grade glioma that is common in children. Intraventricular location is extremely rare. Case Description: We report a case of a young man, 19-year-old, that was admitted to our department for symptoms of increased intracranial pressure. Magnetic resonance imaging (MRI) of the brain revealed a large intraventricular mass within the left lateral ventricle which appears dilated and enlarged. The patient underwent right‑sided frontal craniotomy for resection of the tumor. The resected mass was histologically diagnosed as pilocytic astrocytoma. Postoperatively, the patient had an uneventful evolution and was discharged without any neurological symptoms. Conclusion: Although rare, PA should be considered as a differential diagnosis of large intraventricular tumors.
