A case of central neurocytoma with spontaneous intraventricular hemorrhage is reported. A 23-year-old man, 2 years after experiencing intraventricular hemorrhage, developed severe headaches. The magnetic resonance image showed a mixed intense mass in the lateral ventricle with associated hydrocephalus. The tumor mass was totally removed. The tumor was histologically diagnosed as central neurocytoma. Review of the computed tomography taken 2 years ago showed not only the hemorrhage but also a mass in the left lateral ventricle. This emphasizes that central neurocytoma should be considered in the differential diagnosis of patients with either intraventricular hemorrhage or hemorrhagic tumor.
