There is cortically based, bubbly, lobulated, mass at the posterior part of the left frontal bone measuring (27 x 16 x 16 mm), shows focal rim enhancement of the small part of the tumour (10 x 6 mm), but shows no restricted diffusion neither mass effect. The mass shows suppressed centre on FLAIR with a rim of hyperintense signal but no surrounding oedema, picture suggestive of DNET.
Differential diagnosis is multinodular and vacuolation neuronal tumour.
Case Discussion
The 'bubbly' appearance can be seen also in multinodular and vacuolating neuronal tumours (MVNT) which are however in the juxtacortical white matter, rather than in the cortex.
