title: Concurrent schwannoma and intradural neuroma after resection of a cauda equina schwannoma. A case report and first description.
abstract: OBJECTIVE
  We present the case of a 33-year-old female complaining of recurrent pain and sensory disturbance in both legs, 3 years after the removal of a schwannoma at the level of L2/3.
  
  
  METHODS
  Magnetic resonance imaging showed two lesions at the site of the previous operation. Assuming tumour recurrence, the patient was referred for surgery.
  
  
  RESULTS
  Intraoperatively, both an intradural neuroma and a schwannoma were found. Histopathological assessment confirmed the diagnosis of both coexisting entities.
  
  
  CONCLUSIONS
  Neuroma should be considered in the differential diagnosis of spinal lesions, particularly in the assumption of recurrence.
