Figure 11. Follow up CT scan. Biliary duct dilatation and the cholangiocarcinoma are both visualized on this image. On CT, the mass was 4 cm in length.
Diagnosis: Cholangiocarcinoma
The interpreting radiologist who read the ultrasound conceded our initial findings as well as recommended a follow up CT scan to help further evaluate if the mass was extrinsic or intrinsic in nature.
The CT scan showed a normal appearing gallbladder without cholelithiasis or other pathology.
Cholangiocarcinoma is a carcinoma of the bile duct.
When considering a list of possible differential diagnoses, choledocholithiasis was the first possibility.
