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 tumor (10 x 6 mm), but shows no restricted diffusion neither mass effect. The mass shows suppressed center on FLAIR with a rim of hyperintense signal but no surrounding edema, picture suggestive of DNET.
Differential diagnosis is multinodular and vacuolation neuronal tumor.
Case Discussion
The 'bubbly' appearance can be seen also in multinodular and vacuolating neuronal tumors (MVNT) which are however in the juxtacortical white matter, rather than in the cortex.
