Preferred Label : caudate lobe of liver;
Uberon definition : The caudate lobe (posterior hepatic segment I, Spigelian lobe) is situated upon the
postero-superior surface of the liver on the right lobe of the liver, opposite the
tenth and eleventh thoracic vertebrae. It is bounded on the left side by the physiological
division of the liver called the ligamentum venosum. It is bounded, below, by the
porta; on the right, by the fossa for the inferior vena cava; and, on the left, by
the fossa for the ductus venosus. It looks backward, being nearly vertical in position;
it is longer from above downward than from side to side, and is somewhat concave in
the transverse direction. The caudate process is a small elevation of the hepatic
substance extending obliquely and laterally, from the lower extremity of the caudate
lobe to the under surface of the right lobe. It is situated behind the porta, and
separates the fossa for the gall-bladder from the commencement of the fossa for the
inferior vena cava. Budd-Chiari syndrome, caused by occlusion of hepatic venous outflow,
can lead to hypertrophy of the caudate lobe due to its own caval anastomosis that
allows for continued function of this lobe of the liver. [WP,unvetted].;
