title: Atypical neurocytoma of the spinal cord in a young child.
abstract: BACKGROUND
  Extraventricular neurocytoma is a well-established entity, and non-classical sites like the cerebellum and spinal cord have occasionally been reported.
  
  
  METHODS
  We report a rare case of intramedullary neurocytoma in an 8-year-old boy who presented with paraparesis and urinary incontinence. This tumour was isointense on T1-weighted image and hyperintense on T2-weighted image, and showed heterogenous contrast enhancement.
  
  
  RESULTS
  Pathological examination showed atypical histology in the form of vascular endothelial proliferation, increased proliferation index, mitosis and necrosis.
  
  
  CONCLUSIONS
  Atypical location, younger age and histopathological features are some of the interesting findings in this case, which need to be documented. To the best of our knowledge, this is the youngest patient of spinal cord neurocytoma.
