Sumario:Papillary glioneuronal tumor (PGNT) is a rare brain tumor grouped under mixed glioneuronal tumors according to the World Health Organization Classification of the Central Nervous System. The natural history of this pathology is not yet well documented. We report a case of PGNT that increased in size after a follow-up period of 10 years. An enlarged cyst wall and nodule showed a low intensity signal on T2*-weighted, suggesting hemorrhage during the clinical course. Characteristic pathological findings along with absence of BRAF(V600E) mutation identified the tumor as PGNT. The tumor characteristics of PGNT are discussed based on the presented case, with reference to the existing literature.
