Background and Objective: A sound knowledge of the normal and variant liver anatomy is a prerequisite to having a favourable surgical outcome. A possibility of the presence of the abnormal liver has to be kept in mind when an unexplained abdominal mass is encountered. Although the lobar anatomy of the liver has been extensively researched, very few studies have dealt with lobar anomalies of liver.The present study is aimed to know various lobar anomalies of liver. Methods: The present study was done using 40 formalin–fixed livers in the department of Anatomy, NMC, Raichur. Results: It was observed that elongation of left lobe of liver was seen in 2 cases, Reidel’s lobe was observed in 1 case, quadrate lobe was absent in 2 cases and was ill-defined in 1 case. Conclusion: This study has been done to serve as a guide for proper interpretations of liver images using various imaging modalities. It will also be useful to the operating surgeons to be aware of the frequently occurring morphological variations of liver
