There is a nonenhancing intra-axial T1 hypointense/T2 & FLAIR hyperintense lesion centred on the left parietal operculum in the superficial subcortical and juxtacortical white matter. The lesion consists of groups of several nodules, especially along its internal margin. There is no cortical involvement. There is no diffusion restriction and no mass effect.
The intracranial appearances are otherwise unremarkable.
