By reviewing our cases and previous reports, we describe 4 neuronal and mixed neuronal-glial tumors (papillary glioneuronal tumor, extraventricular neurocytoma, rosette-forming glioneuronal tumor of the fourth ventricle, and glioneuronal tumor with neuropil-like islands), angiocentric glioma and papillary tumor of the pineal region, with an attempt to explain the pathological basis of the imaging features.
