A Comprehensive View into a Novel, Accessory Liver Lobe
Precise clinical knowledge of liver anatomy is required to perform a hepatectomy, in both open and laparoscopic surgery. Accessory liver lobes (ALL) are anatomical variations involving supernumerary lobes in the liver. Although their origin is not entirely understood, hypotheses for the embryological processes resulting in an ALL include hyperplastic anomaly during embryological development or formation because of increased intraabdominal tension from trauma or surgery. In most cases, the accessory lobe is located inferior to the liver. Riedel’s lobe is the best-known example of an accessory lobe, corresponding to hypertrophy of liver segments V and VI. In this report, we presented the case of an elderly female cadaver who showed an atypical ALL left variant attached through an accessory ligament. Therefore, we discuss the gross morphology, histopathology, and clinical and surgical implications to improve future patient outcomes.
