The right lobe is a part of the liver structurally characterised by its position rightward of the middle hepatic vein functionally characterised by contribution to the larger whole part of liver divided into anterior and posterior segments.

anterior segment
The anterior segment of the liver is a segment of the right lobe of the liver. Structurally characterised by its position between the right hepatic vein posteriorly and the middle hepatic vein anteriorly Functionally characterised by contribution to the larger whole. It is part of the right lobe and is made up from subsegments, lobule Common diseases include disease processes affecting the liver at large. Clinical presentation includes pain if the capsule is involved. Diagnostic studies include US, CT, MRI. Treatment is commonly by surgery and laparoscopic surgery.
posterior segment
The posterior is a part of the right lobe of the liver structurally characterised by its position posterior to the middle hepatic vein anterior segment of the right lobe functionally characterised by contribution to the larger whole part of liver divided into subsegments common diseases include disease processes that effect the liver at large cirrhosis hepatitis fatty change metastasis clinical presentation pain if capsule involved diagnostic studies include US, CT, MRI treatment is commonly by surgery, laparoscopic surgery
size
The right lobe is variably sized. An overall transverse diameter of the whole liver of 20-22.5cms, is therefore very variable.
shape
The right lobe is quadrilateral in shape The right lobe lies posterior to the left lobe.
position
The right lobe lies posterior to the left lobe.

The
Riedel’s lobe is a variant an inferior extension of the right lobe of the liver occurring more commonly in women. It is a normal anatomic variant and its presence changes both the size and shape of the right lobe of the liver.
