What are your differentials for a cystic temporal lesion in a young patient presenting with seizures?
Differentials would include cystic tumours such as DNET or small cystic glioma.
Small cystic foci measuring 4 and 2 mm respectively are seen involving cortex and subcortical region of the right Heschl's gyrus. These areas do not fully FLAIR suppress. On the FLAIR sequence, there is a poor definition of the adjacent grey matter with mild regional FLAIR hyperintensity. Mild mass effect. Several punctate foci of FLAIR hyperintensity in the supratentorial white matter are non-specific, but borderline prominent for age. History of migraines? No other focal lesion is identified.
