Anatomically, the Riedel lobe of the liver is a downward tongue-like projection of the anterior margin of the right lobe of the liver to the right of the gallbladder. Accessory liver lobes are uncommonly described and occur from the liver's overdevelopment. The presence of an accessory hepatic lobe is typically discovered by chance, especially in pedunculated forms, when it develops torsion. The auxiliary lobe is usually found below the liver, or infrahepatic. The most well-known example of an auxiliary lobe is Riedel's lobe, which corresponds to hypertrophy of segments V and VI. As indicated in the literature, accessories lobes can mimic tumours and can even produce hepatocellular tumours. As a result, Riedel's lobe may not always be latent and should not be overlooked. The goal of this chapter is to bring current and prior research on Riedel's lobe that has been done by researchers up to date, and to compile it for future researchers and physicians to use as quick references.
