“…2). CT shows details of the relationships of the cyst with surrounding structure, particularly when it is located in the region of the distal common bile duct, where it may be obscured by intestinal gas (2,6,8,24). CT with intravenous biliary contrast medium permits a specific diagnosis of cystic ectasia of the bile ducts to be made by demonstrating contrast filling of the cystic spaces, as seen in two of our patients (2-4, 16, 21, 22, 26).…”

Twelve patients and a foetus with congenital bile duct cysts suggested in the majority of cases at routine upper abdominal sonography were examined by two or more of the following investigations: ultrasonorgaphy (10 patients), computed tomography (5 patients), CT-cholangiography (2 patients), oral cholecystography (7 patients), intravenous cholangiography (4 patients), endoscopic retrograde cholangiopancreatography (ERCP) (6 patients) and cholescintigraphy (2 patients). The sensitivity of each investigation for the diagnosis of bile duct cysts was: ultrasound 40 per cent, computed tomography 20 per cent, CT-cholangiography 100 per cent, oral cholecystography 17 per cent, intravenous cholangiography 75 per cent, ERCP 83 per cent and cholescintigraphy 50 per cent. When a bile duct cyst has been suggested by ultrasonography or other examinations, without a conclusive diagnosis being made, CT-cholangiography is recommended as the next examination. In patients with impaired biliary excretion of contrast medium, ERCP may be required to achieve the diagnosis.

“…The majority of 34 patients with choledochocele reported in the literature underwent cholecystectomy without relief of their symptoms before the correct diagnosis was made [1][2][3][4][5][6][7]. It is surprising that the choledochocele has often been missed at surgery even with operative cholangiography [1,2].…”

We report a case of choledochocele associated with choledocholithiasis. The patient became symptomatic when a gallstone was trapped within the choledochocele, causing intermittent biliary obstruction. Endoscopic retrograde cholangiography (ERC) provided the diagnosis and endoscopic sphincterotomy was performed for definite nonoperative treatment. The lesion could not be identified on ultrasound even after its demonstration by ERC. The importance of direct cholangiography in the diagnosis of a choledochocele is discussed.
