title: Iatrogenic Mycobacterium infection after an epidural injection.
abstract: METHODS
  Case report.
  
  
  OBJECTIVE
  Successful excision of the mass and identification of the causative agent by histologic and microbiologic studies.
  
  
  BACKGROUND
  Spinal pain, caused by an infective mass, developed in a 39-year-old man 3 months after an epidural injection for low back pain.
  
  
  METHODS
  Exploratory surgery was performed to remove the mass, and histologic and microbiologic studies were conducted.
  
  
  RESULTS
  The inflammatory mass was excised successfully, and several specimens were examined for bacteriologic presence. Histologic examination of the excised specimen showed chronic granulomatous inflammation, and subsequent microbiologic studies cultured an acid- and alcohol-fast bacillus that was later identified as Mycobacterium fortuitum.
  
  
  CONCLUSIONS
  A review of the literature shows that this is a particularly uncommon micro-organism.
