A Klatskin tumor is located near which anatomical structure?

• A. Adrenal gland
• B. Hepatic hilum
• C. Inferior vena cava
• D. Head of the pancreas

Answer: (B)

A Klatskin tumor, also known as a hilar cholangiocarcinoma, is specifically located at the hepatic hilum, which is the junction where the left and right hepatic bile ducts converge and exit the liver. This tumor arises in the bile ducts and can obstruct the bile flow, leading to symptoms such as jaundice. The anatomical significance of the hepatic hilum is critical for understanding the implications of Klatskin tumors, as they affect bile drainage from the liver. Recognizing the location and its relationship with bile ducts aids in appropriate diagnostic imaging and treatment strategies. This is contrasted with the other options: the adrenal gland, inferior vena cava, and head of the pancreas, which do not have a direct connection to the bile ducts or the specific pathology associated with Klatskin tumors. Understanding these anatomical landmarks is essential for any medical professional working in areas related to abdominal sonography, oncology, or gastrointestinal disease.
