There is a 12mm FLAIR hyperintense lesion within the right frontal white matter immediately anterior to the right lentiform nucleus. A tail of abnormal signal extends to the right lateral ventricle frontal horn. No negative mass effect or central cystic component.
A FLAIR hyperintensity mass is also demonstrated within the right mesial temporal lobe, centred in the amygdala. This predominantly involves cortex but extends into the subcortical white matter. No uncal herniation or ventricular compression.
Neither lesion demonstrates enhancement, diffusion restriction, hemosiderin staining or elevated CBV (not shown). Spectroscopy demonstrates elevated choline and decreased NAA in the right mesial temporal lobe. Incidental left frontal developmental venous anomaly.
Conclusion: The right anteromedial temporal lobe mass has features most suggestive of low grade glioma. The right frontal white matter lesion is more indeterminate and may reflect either a further focus of glioma, a developmental lesion or an incidental ischaemic/demyelinating focus.
