Quadrate lobe of liver

The quadrate lobe is an area of the liver situated on the under surface of the right lobe, bounded in front by the anterior margin of the liver; behind by the porta hepatis; on the right, by the fossa for the gall-bladder; and on the left, by the fossa for the umbilical vein.

It is oblong in shape, its antero-posterior diameter being greater than its transverse.
