The right mesial temporal lobe, involving the medial aspect of the hippocampal head and the amygdala, is expanded by an ill-defined mass with increased T2 signal. No enhancement, blood products or calcification. Increased DWI signal may represent T2-shine-through (no ADC available, unfortunately).
The differential diagnosis is primarily between a DNET and other low-grade cortical tumours (e.g. ganglioglioma/gangliocytoma).
