Choledochal cyst is a congenital malformation of the bile ducts rare, usually seen in childhood. The classic triad of jaundice, abdominal mass and pain is not always present. Case report: A school girl of nine years, with Acute Pancreatitis torpid, unaltered initial abdominal ultrasound, and no conclusive diagnosis of chronic cholecystitis or acalculous cholangitis abdominal and from magnetic resonance tomography, respectively. Referred for endoscopic retrograde cholangiopancreatography, a study that was omitted from control abdominal ultrasound suggestive of choledochal cyst. New requested from magnetic resonance, which displayed no reports cyst and bile duct dilation and terminal hepatocoledoco related aspects. Expectant management is maintained. The patient remains asymptomatic, with reassessment 3 months later. The abdominal ultrasound revealed: fusiform dilatation of the bile duct in its entirety, a finding compatible with type I choledochal cyst Resection was performed, the cyst, cholecystectomy and reconstruction of the bile duct through a hepato-jejunostomy Roux en Y no complications. Liver biopsy reported normal tissue. We conclude that the use of noninvasive imaging tests such as ultrasound is the method of choice due to its sensitivity to determine the presence of cyst and to demonstrate the anatomy of the pancreatic’duct.
