Diffuse Leptomeningeal Glioneuronal Tumor

Preferred Label : Diffuse Leptomeningeal Glioneuronal Tumor;

NCIt synonyms : Disseminated Oligodendroglial-Like Leptomeningeal Tumor of Childhood; DLGNT;

NCIt definition : A relatively slow growing diffuse leptomeningeal neoplasm usually affecting children and adolescents. It is characterized by the presence of clear glial neoplastic cells reminiscent of oligodendroglioma. A neuronal component may be present. The prognosis is variable.;
