Multinodular and Vacuolating Neuronal Tumour (MVNT)
Incidental T2-hyperintense lesion without mass effect in the right occipital lobe. There was neither diffusion restriction nor pathological enhancement.
On an MRI performed for headache, an incidental frontal lobe lesion was identified.
The bubbly T2-hyperintensity and lack of enhancement are typical of MVNT,
The "soap bubble" T2-hyperintense lesion in the left cerebral hemisphere without mass effect, diffusion restriction or enhancemetn was typical of MVNT.
Clustered subcortical hyperintensities in the right occipital pole were identified incidentally.
The appearance, lack of enhancement and stability over four years, were consistent with MVNT.
