P.143 Adult gangliocytoma arising within the lateral ventricle: A case report and review of the literature

Background: Gangliocytomas are rare neuronal tumors with an incidence of less than 1% all CNS neoplasms. They mostly seen in the pediatric age group, localizing within cerebral cortex, most often temporal lobe. Methods: We report a case intracranial gangliocytoma arising lateral ventricle adult patient. Our 66-year-old female patient started experiencing progressive generalized weakness, headaches, and confusion prior to presentation. Her neurological examination did not reveal any focal deficits. MRI brain showed diffusely enhancing lobulated mass situated frontal horn right extension into foramen Monro obstructive hydrocephalus. Results: The underwent interhemispheric trans-callosal approach gross total resection relief her hydrocephalous. Pathological clusters highly pleomorphic neuron-like cells without evidence neoplastic glial cells. Histopathological immunohistochemistry findings were consistent diagnosis (World Health Organization grade 1). Conclusions: low-grade neoplasms that can present older population unusual locations should be included differential whenever suspicious lesion is encountered.
