title: Portal Annular Pancreas: A Rare and Overlooked Anomaly.
abstract: BACKGROUND
  Portal annular pancreas is a rare pancreatic developmental anomaly which is often overlooked at imaging, and often diagnosed retrospectively when it is detected incidentally at the time of surgery. Although the anomaly itself is asymptomatic, it becomes important in cases where pancreatic resection/anastomosis is planned, because of varying ductal anatomy, risk of ductal injury and increased risk of postoperative pancreatic fistula formation.
  
  
  METHODS
  We present imaging findings in a case of portal annular pancreas in a 45-year-old male patient.
  
  
  CONCLUSIONS
  Portal annular pancreas is a rare and often neglected pancreatic anomaly due to a lack of awareness of this entity. With the advent of MDCT and MRI, accurate preoperative diagnosis of this condition is possible.
