What is the most common location for cholangiocarcinoma? A) Distal bile duct near the gallbladder B) Bile duct of the pancreas C) Bile ducts within the liver parenchyma D) Proximal bile duct at the hilum of the liver
Understand the Problem
The question is asking for the most prevalent site for cholangiocarcinoma, which is a type of cancer that affects the bile ducts. Each option represents a different anatomical location related to the bile ducts.
Answer
D) Proximal bile duct at the hilum of the liver
The final answer is D) Proximal bile duct at the hilum of the liver
Answer for screen readers
The final answer is D) Proximal bile duct at the hilum of the liver
More Information
The perihilar region, also known as the hepatic hilus, accounts for 50-60% of cholangiocarcinoma cases, making it the most common location for this cancer.
Tips
When learning about the common locations for cholangiocarcinoma, ensure to differentiate between intrahepatic, distal, and perihilar regions, as each has distinct epidemiological and clinical characteristics.
