title: Pure distant, leptomeningeal metastasis of esthesioneuro-epithelioma.
abstract: BACKGROUND
  Esthesioneuro-epithelioma is a very rare variant of olfactory neuroblastoma that originates in the region of the cribriform plate. Its intracranial manifestation is due to infiltration of the anterior skull base and frontal lobes.
  
  
  METHODS
  The authors describe a 52-year-old man with a history of a subtotally resected right maxillary sinus ethesioneuro-epithelioma 2 years earlier who presented with a left hemiparesis and signs of increased intracranial pressure. CT examination revealed a tumour of the right temporoparietal region. The tumour and its dural attachment were totally removed. The patient made a full recovery postoperatively.
  
  
  RESULTS
  The features of esthesioneuro-epithelioma were found on histopathological examination.
  
  
  CONCLUSIONS
  The intracranial tumour resected was a distant, leptomeningeal metastasis of esthesioneuro-epithelioma. To our knowledge such a documented case has not been published before.
