In this paper we reported two uncommon adult cases of Diffuse Leptomeningeal Glioneuronal Tumors (DLGNTs) diagnosed after DNA-methylation profiling. This study enlarges the clinical and molecular spectrum of DLGNTs which encompass a wide spectrum of tumors that has yet to be fully clarified, and suggest that this terminology appears unsuitable in some cases. These tumors would be further classified in the large group of “gliomas and glioneuronal tumors driven byMAP-Kinase pathway alterations” in the fifth edition of the WHO classification of CNS tumors that is coming soon.
