Myxoid glioneuronal tumor with PDGFRA p.K385 mutation: Radiological insights from two cases

Myxoid glioneuronal tumor represents a newly recognized entity in the 2021 World Health Organization classification of central nervous system tumors. As one of the 14 defined neuronal and glioneuronal tumors, it is molecularly characterized by PDGFRA p.K385 mutation. In this paper, we illustrate computed tomography, conventional and functional magnetic resonance imaging, and positron emission tomography-computed tomography imaging features of two myxoid glioneuronal tumor cases, introducing novel imaging characteristics.
