title: Intraluminal duodenal diverticulum causing acute pancreatitis: CT scan diagnosis and review of the literature.
abstract: BACKGROUND
  Intraluminal duodenal diverticulum is a rare congenital anomaly. First described by Boyd in 1845, no more than 100 cases have been reported up to now: only 17 are associated with acute pancreatitis.
  
  
  METHODS
  A new case of intraluminal duodenal diverticulum with acute pancreatitis is reported and the literature about this association reviewed.
  
  
  RESULTS
  The diagnosis was made by helical CT scan. The pathogenesis of pancreatitis was possibly due to a pure duodenal content reflux through the papilla of Vater. The patient was successfully treated by surgery.
  
  
  CONCLUSIONS
  Intraluminal duodenal diverticulum is a rare but curable cause of pancreatitis, usually affecting young people. We describe, for the first time, its unusual helical CT imaging with two-dimensional reformations.
