Abstract:
Choledochocele is the least common form of choledochal cyst. We report a rare bile duct cyst diagnosed in a 63-year-old woman via CT cholangiography. Although conventional sonography initially failed to reveal abnormal findings, a subsequent detailed study clearly depicted the lesion. To the best of our knowledge, this is the first report of choledochocele unambiguously demonstrated on transabdominal sonography.
