title: Complete large bowel duplication with paraduodenal cyst: prenatal sonographic features.
abstract: OBJECTIVE
  To illustrate diagnostic dilemmas while considering a diagnosis of complete large bowel duplication and duodenal duplication cysts.
  
  
  METHODS
  A case of large bowel dilatation with a peripancreatic cyst was identified sonographically in a 27-year-old gravida 3 at 35 weeks of gestation, suffering from gestational diabetes and pregnancy-induced hypertension.
  
  
  RESULTS
  On the basis of sonographic findings of dilated, hyperperistaltic large bowel loops, and a large cyst with echo-free contents near the pancreas, a diagnosis of large bowel obstruction with a paraduodenal cyst was considered. The findings were confirmed after postnatal ultrasonography. At the time of surgery, it proved to be a completely duplicated large bowel with a paraduodenal cyst.
  
  
  CONCLUSIONS
  Prenatal findings of a hugely dilated, hyperperistaltic large bowel should lead one to suspect/consider large bowel duplication. Associated cysts are likely to be bowel duplication cysts. Timely intervention can thus obviate potentially serious complications.
