Neuroradiological and histopathological findings of intraventricular central neurocytoma

Neurocytoma - a rare intraventricular tumor.

Central neurocytoma presenting with intraventricular hemorrhage: case report and review of literature.

We report a case of a 25 year old man presenting with acute headache, vomiting and nuchal rigidity. Computed Tomography (CT) scan and MRI without contrast showed a right ventricular hemorrhage surrounding a mass lesion. The tumor and hematoma were completely removed by neurosurgical transcortical-transventricular approach. Anatomopathological analysis revealed a central neurocytoma. Central neu...

MR Spectroscopy to Distinguish between Supratentorial Intraventricular Subependymoma and Central Neurocytoma

PURPOSE The purpose of this study was to discriminate supratentorial intraventricular subependymoma (SIS) from central neurocytoma (CNC) using magnetic resonance spectroscopy (MRS). METHODS Single-voxel proton MRS using a 1.5T or 3T MR scanner from five SISs, five CNCs, and normal controls were evaluated. They were examined using a point-resolved spectroscopy. Automatically calculated ratios ...

Pediatric Central Neurocytoma.

Central neurocytomas are well-differentiated tumors of neuronal origin. These are relatively uncommon in the pediatric population. Anaplastic features reflected by brisk mitotic activity, microvascular proliferation, necrosis, and MIB-1 labeling index >2% or 3% have been proposed to indicate aggressive behavior. Because of its rarity, there is paucity of data regarding the histologic spectrum a...

Neurocytoma accompanied by intraventricular hemorrhage: case report and literature review.

Neurocytomas are a rare subset of primary cerebral neuroblastomas. They occur within the ventricles of young adults, may calcify , and demonstrate a better prognosis than do their parenchymal counterparts . Of the 21 patients reported in the literature who appear to meet most of the criteria for th is diagnosis, 18 had symptoms referable to increased intracranial pressure [1-1 0]. The lesions w...
