Distinguishing a PA from a DLGNT represents a diagnostic challenge, particularly in this spinal location, since these two tumours (respectively, circumscribed astrocytic and disseminated glioneuronal) [48], share a similar clinical presentation (a spinal tumuor associated or not with leptomeningeal dissemination at diagnosis) [1, 5, 20, 28, 32, 35], histopathological (oligodendroglial-like morphology with Olig2 and synaptophysin expressions), and molecular features (Mitogen-Associated Protein Kinase (MAPK) pathway alteration) [48]. Here, OLIG2 is linked to neoplasm.
