How does a choledochal cyst clinically present?
Jaundice, abdominal pain, palpable abdominal mass.
There is diffuse fusiform dilation of the common hepatic duct and the common bile measuring 15 mm in the maximum diameter and measuring 5 mm at its distal end. Also, noted is mild diffuse prominence of the left hepatic duct measuring 2-3 mm in maximum diameter and diffuse prominence and tortuosity of the cystic duct. The constellation of findings with fusiform dilation and tortuosity of common hepatic duct and common bile duct is concerning for type I fusiform choledochal cyst. The possibility of type IVB choledochal cyst with cystic dilation versus cysts of the distal CBD is also considered.
The gallbladder is normal. No gallstones or discrete extrinsic compression. No focal lesion in the liver. The liver appears normal in size and signal intensity.
No acute process in the abdomen and pelvis.
