title: Ultrasonographic diagnosis of congenital membranous jejunal stenosis and gastric duplication cyst in a newborn: a case report.
abstract: BACKGROUND
  Congenital jejunal stenosis and gastric duplication cysts are very rare congenital anomalies of the gastrointestinal tract in the newborn. We present a case of congenital membranous jejunal stenosis associated with gastric duplication cysts, which was diagnosed by ultrasonography. To the best of our knowledge, this is the first report of ultrasonographic diagnosis of congenital membranous jejunal stenosis associated with a gastric duplication cyst in a newborn.
  
  
  METHODS
  A 1-month-old Chinese baby girl presented with projectile vomiting and hyperpyrexia for 3 days. An upper gastrointestinal contrast study showed incomplete duodenal obstruction; however, ultrasonography revealed congenital membranous jejunal stenosis associated with a gastric duplication cyst. After surgical excision of the jejunal membrane and gastric duplication cyst, she recovered well with no bilious vomiting at the 1-year follow-up.
  
  
  CONCLUSIONS
  Ultrasonography is a useful tool for the evaluation of membranous jejunal stenosis and the identification of small, asymptomatic gastrointestinal duplication cysts.
