What was the medial segment formerly called?

The medial segment of the left lobe was historically called the quadrate lobe. This name comes from its quadrilateral shape on the visceral surface and its position between the gallbladder fossa (to the right) and the fissure for the ligamentum teres (to the left), with the porta hepatis above. In old anatomy texts, this region was referred to as the quadrate lobe, whereas in modern terminology it corresponds to the left lobe’s medial sector (segment IV in the Couinaud system).
