Case Report Lateral ventricular chordoid glioma in a pediatric patient: a case report and literature review

Chordoid glioma is a rare tumor exhibiting both glial and chordoid features. This entity is generally considered to occur exclusively in the region of the third ventricle, however, that arising in the lateral ventricle is extremely rare. Herein, we report a case of lateral ventricular chordoid glioma in a pediatric patient. Additionally, relevant literatures were reviewed. An intracranial space-occupying lesion was discovered in a 10-year-old asymptomatic boy. Brain computed tomography (CT) and magnetic resonance imaging (MRI) revealed a nodular mass in the frontal horn of the right lateral ventricle. Histopathological examination and immunohistochemical staining were consistent with a diagnosis of chordoid glioma. No adjuvant radiotherapy or chemotherapy was performed. Preoperative identification of chordoid gliomas depending on neuroradiological profiles is challenging, and definitive diagnosis still needs histopathological evidence. Surgical resection should be the choice of treatment, and prognosis is favorable.
