Introduction: the papillary glioneuronal tumor (PGT) is an uncommon disease and it has recent categorization. It has probable origin in the pluripotent stem cells of the subependymal zone that is located mainly around the temporal horns of the lateral ventricles. In these zones typically are presented these neoplasms. Case record: an atypical case of PGT is presented in a patient with 48 years old, in who the tumor compromised the inferior cerebellar vermis and both cerebellum hemispheres. Conclusion: the PGT is generally located in the supratentorial area. However, it has been indicated the existence of pluripotent stem cells of the subependymal zone, around the area postrema, at the median eminence in the floor of the fourth ventricle and in the choroid plexus, which could explain the exotic occurrence of the PGT in the posterior fossa Rev.cienc.biomed. 2015;6(1):150-154 KEYWORDS Neurosciences; Central nervous system; Brain neoplasms.
