Right temporo-insular T2 hyperintensity is identified. This is associated with gyral and possibly leptomeningeal enhancement in the anterior temporal pole and anterior insula. No associated diffusion restriction or convincing CBV increase. Left hippocampal formation demonstrates subtle FLAIR hyperintensity, raising the possibility of contralateral involvement. Remainder of the brain is normal. No region of diffusion restriction to suggest acute infarct. Incidental right maxillary sinus mucous retention cyst.
