title: A late and extreme complication of lumboperitoneal shunt.
abstract: BACKGROUND
  Lumboperitoneal (LP) shunting is an effective treatment modality for commmunicating hydrocephalus, pseudotumor cerebri, postoperative pseudomeningoceles, and cerebrospinal fluid fistulas. However, LP shunts are associated with some complications. Here, we report an extreme complication resulting in the formation of granulation tissue.
  
  
  OBJECTIVE
  To report a late extreme complication of LP shunt.
  
  
  METHODS
  A case report.
  
  
  METHODS
  A late and unusual complication of an LP shunt with unique radiologic findings is presented.
  
  
  RESULTS
  Spinal magnetic resonance imaging studies depicted a mass on the right anterior section of the dural sac encircling the catheter throughout its course from the L3-L4 interspinous level to the catheter tip.
  
  
  CONCLUSIONS
  The etiopathologic mechanism, the prolonged duration, and the unusual radiologic findings in this case are unique and remarkable.
