title: Atypical extraventricular neurocytoma:A report of two cases.
abstract: Central neurocytomas are tumors with neuronal differentiation, generally arising in the lateral ventricles in the region of foramen of Monro. Whenever these tumors arise in the brain parenchyma they are called "extraventricular neurocytomas". We present two unusual cases of extraventricular atypical neurocytomas at uncommon locations with a very high Ki-67 index. The WHO grading of this tumor is yet to be answered.
