Background and Aims. Anomalous structures of the liver are
incidentally detected during autopsies or during routine cadaveric
dissection. The present study aimed to observe the abnormal shapes of
quadrate lobe, accessory sulci and ligamentum teres of the liver. Materials and Methods. A total of 20 formalin fixed cadaveric
livers (n=20), irrespective of the sex, were taken for this study. These
specimens belonged to cadavers of unknown origins. The presence
of accessory sulci and abnormalities related to the quadrate lobe and
ligamentum teres were studied in detail. Morphometric measurements
were taken for the abnormal accessory sulci and abnormal quadrate
lobes. Results. Variable shapes of the quadrate lobes were observed with
8 (40%) being rectangular, 6 (30%) being pear-shaped, 4 (20%) being
triangular and another 2 specimens (10%) which were square in shape.
The presences of accessory sulci on the diaphragmatic surface of the
liver were observed in 2 specimens (10%). Ligamentum teres traversed
the groove in 18 (90%) while in 2 (10%) specimens, the ligamentum
teres was embedded in the groove and it was covered by parenchymatous
tissue of the liver it from the side of the quadrate lobe. Conclusion. Prior anatomical knowledge of the presence of the
anomalous structures in the liver with may be helpful for the radiologist
and surgeons for correct interpretation of radiographs and planning
appropriate hepatobiliary surgeries. Clin Ter 2013; 164(3):197-201.
