Multinodular and vacuolating neuronal tumour (MVNT): Case report of a rare epileptogenic brain tumour

Abstract

Multinodular and Vacuolating Neuronal Tumours (MVNT) are newly described entities with distinct radiological patterns and cytoarchitecture. These are associated with epilepsy although most are usually asymptomatic. We present a case of a 55 years old male with new onset seizures and altered sensorium. No electrolyte imbalances were present or any previous history of seizures given. MRI of the brain revealed subcortical tiny nodular cystic lesions suggesting a probable MVNT rather than a Dysembryoplastic Neuroepithelial Tumour (DNET) due to the subcortical location. No surgical intervention was recommended. The patient was stable on antiepileptics.
