Disseminated Glioneuronal Tumor: A rare presentation in children

Gliomas, though most common pediatric central nervous system tumor, can manifest as disseminated glio-neuronal tumor, a rare variant in children. Clinical presentation depends on its location, type and age of child. We are presenting 8 years old male child with fever, projectile vomiting and severe headache which woke him up from deep sleep for 1 month. He had positive meningeal signs and raised intracranial tension with cerebrospinal fluid picture suggestive of partially treated meningitis. There was no improvement even on adequate duration of intravenous antibiotics and had appearance of new onset false localizing signs, MRI brain showed features of cryptococcal meningitis for which India ink staining was negative. As clinical picture was unlike of meningitis, repeat 3 tesla MRI brain was done. Expert neuro-radiologist’s opinion was in favor of disseminated glio-neuronal tumor which was confirmed on histopathological examination. Child underwent laminectomy in TATA memorial hospital and advised palliative care. Child succumbed at home within 6 months of illness.

Multinodular and vacuolating neuronal tumor of the cerebrum: three case reports

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.
