title: Papillary glioneuronal tumor: unexplored entity.
abstract: Papillary glioneuronal tumors represent a new and rare entity of an uncommon morphologic subtype of low-grade mixed neuronal-glial neoplasms with an unclear etiology. They are described as benign lesions with extraventricular localization. We report the second case of papillary glioneuronal tumor with recurrent nature after gross-total resection, and the third case of this tumor with intraventricular localization. While conventional magnetic resonance imaging of papillary glioneuronal tumors is well described in literature, there are no data based on advanced magnetic resonance techniques. The present article represents a review of clinicopathological and both conventional and advanced magnetic resonance imaging characteristics of papillary glioneuronal tumors, with focus on 2 cases with atypical course and localization.
