A mini accessory liver lobe in the fissure for ligamentum teres and its clinical significance: a case report.

The liver can present a number of congenital anomalies. More common among them are the irregularities of the shape and the number of lobules. The less common variations include the presence of accessory lobes or accessory livers. The accessory lobes may be attached to the liver through a mesentery or a bridge of the hepatic tissue and they are usually asymptomatic. An accessory liver lobe is a very rare occurrence and when it exists, it becomes clinically important because of its rarity. We are reporting here the presence of a very small accessory liver lobe and have discussed its clinical relevance. We observed a mini liver lobe which was situated in the posterior part of the fissure for ligamentum teres. It was triangular in shape and about one inch in width. It was attached to the left anatomical lobe of the liver through a vascular pedicle which contained the branches of hepatic artery and portal vein and hepatic duct. Histological sectioning revealed the normal liver architecture in the accessory lobe. The knowledge of this accessory lobe could be of use to surgeons and radiologists.
