Choledochal cyst type IVa
Updates to Study Attributes
There is significant cystic dilatation of the main right and left biliary ducts with branching of the left duct versus distortion/displacement of the right hepatic duct due to a dilated right posterior duct. There is a focal area of dilatation in the suspected right posterior duct, measuring up to 1.6 cm. There appears to be a "waist"/area of narrowing just proximal to the "branching of the left ducts", with the left-sided ducts measuring 6.6 and 7.6 mm. The common bile duct is tortuous and dilated measuring 1.5 cm and tapers towards the ampulla with andan intermediate-decreased signal in the distal CBD, most consistent with debris/sludge. There appears to be a dilated tortuous cystic duct measuring 1.1 cm just proximal to entering the CBD. The gallbladder is distended with high signal debris within the distal portion of the gallbladder with intermediate-decreased signal within the remaining gallbladder, consistent with the patient s known inspissated bile/debris. There is visualization of a slightly serpiginous, mildly dilated main pancreatic duct, measuring 2.2-2.4 mm; without dilatation of the branching ducts.
