Question

Cholecystocaval line separates:

• A. Right & Left liver lobe
• B. Liver with Gall Bladder
• C. Right Lobe of Liver with Gall Bladder
• D. Left Lobe of Liver with Gall Bladder

Hint:

Gall bladder fossa to IVC groove = Cantlie line, the functional lobar divide.

Answer 1

The Correct Option is A

Step 1: Recall functional liver anatomy. The liver is divided into functional right and left lobes, which differ from the anatomical lobes defined by the falciform ligament. Step 2: The functional right and left lobes are separated by an imaginary plane running along the floor of the fossa for the gall bladder and the groove for the inferior vena cava - this is the cholecysto-caval line (Cantlie line). Step 3: On the anterosuperior surface the plane passes a little to the right of the attachment of the falciform ligament, and the resulting functional right and left lobes are roughly equal in size. Step 4: So the cholecystocaval line separates the right and left lobes of the liver, making option a correct; the other options misstate the structures the line divides.
