Classifying Choledochal Cysts Using Hepatobiliary Scintigraphy

Abstract

This study illustrates the utility of hepatobiliary scintigraphy in diagnosing type 1 and 4 choledochal cysts.

Spontaneous rupture of a type IVAcholedochal cyst in a young adult during radiological imaging

“…In addition, it contributes to the diagnosis of CC, although such studies are practically acquired in a limited number of patients. Rajnish et al [4] evaluated the efficacy of hepatobiliary scintigraphy in classifying CC patients with confirmed Todani types I and IV cysts and found that it has a good accuracy in the diagnosis, correlating with ERCP or surgical findings in 86% of the cases. The false negative results are mainly attributable to its limitation in identifying Abdominal MRI (spin echo T2-weighed, transverse projections -A and B, coronal projection -C) displaying bile leakage into the peritoneal cavity (arrowheads).…”

Radionuclide applications in paediatric gastroentrology

“…Endoscopic retrograde cholangio-pancreatography (ERCP) is regarded as the gold standard amongst investigations for diagnosis and classifying choledochal cysts. Hepatobiliary scintigraphy has the advantage of imaging the entire biliary tree in its long axis, similarly to ERCP, but in a noninvasive way 3,11 . Occasionally an ovarian cyst, mesenentric cyst, bowel duplication cyst, pancreatic pseudocyst or duodenal diverticulum may mimic a choledochal cyst by virtue of their location.…”

Value of Hepatobiliary Scintigraphy After Type 1 Choledochal Cyst Excision and Roux-en-Y Hepatojejunostomy
