title: Contrast layering in a choledochal cyst: a new CT observation.
abstract: A choledochal cyst is an uncommon congenital abnormality and may present with a wide range of clinical symptoms. I here report a new finding from the use of computed tomography, namely layering of intravenous contrast agent within the cyst. This direct sign gives a definitive diagnosis when clinical or other imaging features may not clearly establish the diagnosis.
