title: Schwannoma of the nasal septum presenting as a multicentric neuronal tumour.
abstract: OBJECTIVE
  Schwannomas (neurilemmomas) are benign primary tumours that arise from Schwann cells. Schwannomas arising from the nasal septum are exceptionally rare. Here, we report a unique case of schwannoma of the nasal septum presenting as a multicentric neuronal tumour.
  
  
  RESULTS
  A 40-year old male sustained intermittent left tinnitus. Magnetic resonance imaging revealed masses near the nasal septum and upper cervical cord in addition to a tumour in the left cerebellopontine (CP) angle. The tumour in the nasal septum was completely resected by endoscopic endonasal surgery and diagnosed as a typical schwannoma. The CP angle tumour was treated with stereotactic radiosurgery, while the asymptomatic cord lesion showed no significant growth and remains under observation.
  
  
  CONCLUSIONS
  Endoscopic endonasal surgery is useful for the resection of schwannomas of the nasal septum. Schwannomas of the nasal septum may present as multiple neuronal tumours.
