title: Solitary eosinophilic granuloma of the adult lumbar spine.
abstract: BACKGROUND
  Eosinophilic granuloma (EG) is a benign bone tumor that rarely occurs in adults. It is usually found occurring in flat and long bones, but spine is often affected too. EG is of unknown aetiology, and the course of the disease is unpredictable.
  
  
  METHODS
  Two cases of EG of the adult lumbar spine are reported, representing a difficult challenge for diagnosis and treatment.
  
  
  CONCLUSIONS
  CT scan guided trocar biopsy allowed to achieve a definitive diagnosis, and CT scan guided intralesional infiltrations of corticosteroids were the successful treatment.
