What are neuronal and glio-neuronal tumors?

Far less frequent than gliomas Composed of cells with neuronal characteristics Typically lower-grade lesions that often present with seizures. While some neuronal differentiation can be observed in many tumors, lesions in this group are primarily composed of cells that express neuronal markers, such as synaptophysin and neurofilaments. Central neurocytoma : is a low-grade neoplasm found within and adjacent to the ventricular system (most commonly the lateral or third ventricle); it is characterized by evenly spaced, round, uniform nuclei and often islands of neuropil
