Choledochal cysts: evaluation with MR cholangiography

Abstract

MR cholangiography can be used to confirm the diagnosis of choledochal cysts and define the extent of involvement preoperatively. The pancreatobiliary junction, however, is difficult to visualize. Non-biliary cysts such as a hydatid cyst can mimic a choledochal cyst on the MR cholangiogram and should be correlated with the MR cross-sectional images to avoid misinterpretation.

Using MR Cholangiopancreatography to Reveal Anomalous Pancreaticobiliary Ductal Union in Infants and Children with Choledochal Cysts

“…MR cholangiopancreatography is a noninvasive procedure and provides the best available projection image for revealing the extent of choledochal cyst in children and adults [8][9][10][11][12][13][14][15]. Researchers have reported that anomalous pancreaticobiliary ductal union can be depicted in adult patients on MR cholangiopancreatography with a half-Fourier single-shot fast spin-echo or turbo spin-echo sequence [12,13,15], but that this finding was not shown in children when a turbo spin-echo or an inversion recovery turbo spin-echo sequence with maximum intensity projection was used [9,10].…”

Due to those improvements, contemporary detection rates are possibly higher than what our cumulative data indicates.…”

MR imaging findings of ciliated hepatic foregut cyst: an unusual cause of fluid-fluid level within a focal hepatic lesion (2005:4b)

“…Pancreatic pseudocyst can be confirmed or excluded on the basis of clinical history and presentation. Choledochal cyst and gallbladder duplication can be correctly diagnosed with MR imaging if the lesion is found to communicate with the biliary duct system [10,11].…”
