title: Intra-bronchial migration of peritoneal catheter of lumboperitoneal shunt.
abstract: BACKGROUND
  A rare case of intra-bronchial migration of peritoneal catheter of lumboperitoneal (LP) shunt was treated under the bronchoscopic and fluoroscopic observation.
  
  
  METHODS
  A 71-year-old man, who underwent LP shunt installation due to idiopathic normal pressure hydrocephalus a year before, presented with history of high fever and sputum production. Roentgenography and computed tomography of the chest revealed migration of distal end of the peritoneal catheter into the left main bronchus. Migrated catheter was gently extracted through the abdominal wound incision under the bronchoscopic and fluoroscopic observation. Contrast material infused into the catheter did not spread into the pleural cavity. The patient was free of the symptoms within 2 postoperative weeks. Moreover, he underwent the ventriculo-peritoneal shunt surgery 1-month later.
  
  
  CONCLUSIONS
  This is the first case of the migration of peritoneal catheter of LP shunt into the main bronchus.
