One case of myxoid glioneuronal tumour in the left frontal lobe.

Myxoid glioneuronal tumour (MGNT), previously described as dysembryoplastic neuroepithelial tumour of the septum pellucidum, was classified as a new tumour type in the fifth edition of the WHO Central Nervous System Tumor Classification of 2021. This classification was based on its anatomical location, imaging features, and genetic characteristics. MGNTs are clinically rare and prone to misdiagnosis. In this report, we present a case of MGNT in the left frontal lobe, which was confirmed through surgical pathology.
