[Uncommon presentation of central neurocytoma causing intraventricular hemorrhage: case report]

Abstract

Central neurocytoma was first described by Hassoun et al. in 1982 as a well-differentiated tumor from neuronal origin. This tumor typically occurs in young adults, localized in the ventricular system. It usually presents as intracranial hypertension due to obstructive hydrocephalus. The differential diagnosis should be done with others intraventricular tumors as oligodendroglioma, subependymoma and choroidal plexus papilloma. There are few cases of central neurocytoma presented by intraventricular hemorrhage in the literature. We report a case of 35 year-old woman, who presented with obstructive hydrocephalus due to intraventricular hemorrhage within the tumor. MRI revealed a tumor localized in the right lateral ventricle. Histopathological and immunohystochemical analysis confirmed the diagnosis of central neurocytoma. We review options for the treatment of this entity as well reinforce the inclusion of central neurocytoma as a differential diagnosis for intraventricular hemorrhage.
