Cervical Medulloblastoma mimicking a nerve sheath tumour in a child: A rare extracranial presentation

Abstract

Medulloblastoma is the most common malignant pediatric brain tumour, accounting for nearly 20% of all childhood intracranial neoplasms. It is classified as an embryonal tumour and most commonly arises in the cerebellar vermis or hemispheres of children.¹ The 2021 World Health Organisation (WHO) classification recognises medulloblastoma as a molecularly heterogeneous entity with distinct clinical and prognostic implications.¹^,³

Primary extracranial or spinal medulloblastomas are exceedingly rare, with only isolated case reports and small series described in the literature.?^-? Cervical spinal presentation without intracranial disease is particularly uncommon and often leads to diagnostic confusion.?
