Follow-up magnetic resonance imaging of the brain at our institute 8 months after the onset of the symptoms. A T2W axial image of the brain at the level of the basal ganglia shows T2 hyperintense cystic structures in the right temporal operculum and the anterior interhemispheric fissure as pointed out with the help of black arrows. B Axial FLAIR image of the brain at the level of the basal ganglia shows the signal suppression in the cystic lesions on FLAIR as compared with T2W image shown in A. This finding is pointed out with the black arrows. C Post-contrast T1W axial image of the brain at the level of basal ganglia shows no evidence of enhancement of the cystic structures, pointed out with white arrows. These cystic structures may represent encysted or loculated CSF
