Anomalies of the liver are uncommon and for the most part consist of variations in the size and configuration of the true right and left lobes, such as marked elongation of the right lobe producing the so-called Riedel's lobe, or of the surface markings which define the quadrate and caudate lobes. Accessory lobes may also occur, usually as small, tongue-like projections from the surface of the liver in the vicinity of the gallbladder fossa, or less frequently as isolated lobes which are connected with the liver by a pedicle or mesentery containing its vascular supply and hepatic duct, if it has one. It is unusual for such a lobe to produce symptoms. We are reporting one such case. A review of the literature reveals only one other report of such an occurrence.
