Multinodular and vacuolating neuronal tumor (MVNT) of the cerebrum is a seizure-associated rare lesion that currently appears to be a malformative lesion or hamartoma rather than a low-grade neoplastic lesion. MVNT pathognomonic magnetic resonance imaging (MRI) features allow for diagnostic accuracy in the differential diagnosis. Lesions are usually asymptomatic, nonprogressive and incidentally found requiring only imaging monitoring over time. Although uncommon, it is important to be familiar with MVNT clinical presentation and key imaging features. We here present a series of three cases with imaging findings similar to those described in the literature. These patients were followed with serial neuroimaging.
