We report a case of central neurocytoma that manifested tumor recurrence with craniospinal dissemination. Imaging studies before surgery showed markedly enhanced small cysts and calcification, which invaded the adjacent brain parenchyma, located in posterior horn right lateral ventricle. Proton MR spectroscopy elevated choline lactate peaks strongly diminished N-acetylaspartate peak. Two years after neurosurgical intervention, multiple dissemination middle cranial fossa intradural extramedullary space spine.
