Introduction: Liver is a wedge shaped visceral organ in the body, occupies right hypochondrium,
epigastric region and extends in to left hypochondrium. A thorough knowledge of anatomy of liver and
its variations will avoid errors in diagnostic imaging and will also help the surgeons design appropriate
surgical approaches.
Materials and Methods: The study was conducted in the Department of Anatomy of our Institution. A
total of 35 numbers of livers removed from cadavers were used for the study. The morphological variations
of liver such as changes in size, shape, presence of accessory lobes, fissures, hypoplastic lobes were noted
and tabulated.
Results: Out of the 35 livers studied, 15 specimens (42.9%) exhibited normal fissures and lobes, 13 (37.1%)
had accessory fissures over different lobes. In 3(8.6%) specimens of liver hypoplastic left lobe was observed
and in 4(11.4%) specimens lingular process of left lobe was observed. There were 8 accessory fissures were
seen in right lobe, 5 in left lobe, 4 in caudate lobe and 5 in quadrate lobe. Out of 35 livers studied, accessory
lobes were observed in 9 liver specimens, which can be grouped as 1 in right lobe, 2 in left lobe, 5 in caudate
lobe and 1 in quadrate lobe.
Conclusion: The authors conclude that morphological variations of liver must be taken in to account by
the Radiologist and G a stroenterologist while making various differential diagno sis as these variations can
present various clinical manifestations/ implications.
