Todani type VI choledochal cysts, originating from the cystic duct, are rare and challenging to diagnose preoperatively. Intraoperative findings confirmed the diagnosis, leading to successful surgical management and patient recovery.

Area of Science:

Gastroenterology and Hepatobiliary Surgery
Diagnostic Imaging
Surgical Case Reports

Background:

Choledochal cysts are congenital dilations of the bile ducts.
Todani type VI choledochal cysts, originating from the cystic duct, represent a rare subtype.
Preoperative diagnosis of type VI choledochal cysts is often difficult due to ambiguous anatomical features.

Observation:

A 35-year-old woman presented with an upper abdominal mass, initially suspected as a Todani type I choledochal cyst based on CT and MRCP.
Intraoperative findings revealed a large cyst arising from the cystic duct, separate from the intra- and extrahepatic bile ducts, consistent with Todani type VI.
The cyst was attached to the gallbladder without connection to the main biliary tree.

Findings:

The study highlights the diagnostic challenges of rare Todani type VI choledochal cysts.

Misdiagnosis as type I or II choledochal cysts is common due to overlapping imaging characteristics.

Intraoperative diagnosis was definitive, enabling appropriate surgical intervention.

Implications:

Accurate preoperative diagnosis of type VI choledochal cysts may necessitate advanced imaging techniques like ERCP in cases of high suspicion.
Understanding the cystic duct anatomy and common bile duct diameter is crucial for surgical planning.
Early and accurate diagnosis and management are key to successful outcomes for this rare condition.
