MRI
The following day, brain MRI was performed, showing an intra-axial mass in the right temporal lobe with extension into the adjacent parietal and frontal lobes. The lesion is estimated to measure 6 cm in size. The brightness on FLAIR extends beyond the borders of the lesion into the adjacent basal ganglia and subinsular white matter and extends posteriorly to the occipital lobe and involves all the white matter structures of the right temporal lobe. This FLAIR signal may represent tumoral edema or true infiltration.
