Inferiorly, the right hepatic lobe is separated from the left lobe by what structure?

• A. Right portal vein
• B. Left hepatic vein
• C. Main lobar fissure
• D. Middle hepatic vein

Answer: (C)

The main lobar fissure is the structure that separates the right hepatic lobe from the left lobe inferiorly. This anatomical feature is an important landmark within the liver, providing a clear demarcation between the two lobes. The main lobar fissure runs from the gallbladder fossa to the inferior vena cava and is significant not only in anatomy but also in various imaging modalities used in ultrasound and other imaging techniques. Recognizing this fissure aids in the assessment and interpretation of liver conditions and structures during a sonographic examination. The presence of the main lobar fissure allows for easier identification of liver segments and is useful in surgical planning and interventional procedures.
