Extracentral Nervous System Metastases from Medulloblastoma

Abstract

Medulloblastoma belongs to the group of highly malignant neuroepithelial tumours and is the commonest tumour in childhood (12–25 %)¹, but is rare in adults (0.4–1%) of all primary brain tumours)^1,2. Medulloblastomas usually arise in the posterior fossa and spread readily throughout the CSF, although 10–30% of patients develop extracentral nervous system metastases ². We describe a 30-year-old woman presenting bone metastases from medulloblastoma located predominantly in the spine.
