title: Spinal extradural metastasis from a medulloblastoma.
abstract: Medulloblastoma metastasising extraxially is a rare entity. The mechanisms that cause such spread are not fully understood. We present a patient who developed a low thoracic metastasis three years after surgical removal of a posterior fossa medulloblastoma. A spinal metastasis penetrated the dura, thus becoming extradural and from this tumour a completely extradural lumbal metastasis developed. Simultaneous local recurrences of systemic metastases were not noted.
