general rad case 3

Findings:

• Axial T2 and FLAIR images show multiple clustered hyperintense foci ('bubbles') in right parietal subcortical white matter
• Post contrast images (not shown) depicted no enhancement within these foci. The foci did not show diffusion restriction on DWI (not shown).

Diagnosis:

Multinodular and vacuolating neuronal tumor (MVNT)

Discussion:

• First described in 2013, MVNTs are considered a type of glioneuronal and neuronal tumors.
• Most lesions are asymptomatic, and some may be associated with epilepsy.
