Medulloblastoma is defined as a malignant, invasive embryonal tumor of　the cerebellum in children, predominantlyneuronal differentiation and inherent tendency to metastasize via CNS pathways. Cerebellar neuroblastoma,albeit very rare, is subclassifed in medulloblastoma with extensive nodularity and advanced neuronaldifferentiation. We have encountered these rare cerebellar neuroblastomas, many cases of which have been examinedultrastrlucturally for more than thirty years. Given hallmarks of neuronal differentiation is the presenceof developing axons and synapse devices, cerebellar neuroblastoma is very rare, and most cases are equivocalneuroblastoma or medulloblastoma. Glial differentiation is none or minimal. Central neurocytoma is a well definedtumor but it should be born in mind that this tumor contains immature neuronal cells, that is neuroblasts,and "some cases are called neurocytoma-neuroblastoma", I consider personally.
