title: Spinal intramedullary metastasis of medulloblastoma at initial diagnosis.
abstract: METHODS
  Spinal magnetic resonance imaging of a 4-year-old boy with medulloblastoma at the initial presentation showed intramedullary lesion without enhancement effect and slight cord swelling from C-5 to T-1. After complete response to the initial therapy, this lesion recurred and slowly expanded. Cervical 11C-methionine-positron emission tomography could establish the diagnosis of intramedullary metastasis.
  
  
  CONCLUSIONS
  Spinal intramedullary metastasis of medulloblastoma at initial diagnosis is extremely rare, but must be considered.
