Abstract: Objective: The objective of this study is to determine the morphological variations of the quadrate lobe, to propose the criteria that make it possible to define the presence or not of the quadrate lobe, the aspects defining the notion of fusion of the quadrate lobe with the right lobe or the left lobe.This study also looks for the different shapes of the quadrate lobe as well as the existence and frequency of fissures within this lobe.This study will improve anatomical knowledge and diagnosis of liver tumors located in this liver segment. Material and Methods:This study was carried out in the necropsy room of the Bichat pavilion of the Aristide Le Dantec University Hospital in Dakar.It involved 39 livers of indigenous adult Senegalese cadaveric subjects whose cause of death was neither liver disease nor liver trauma.On each liver collected, rinsed with water, we observed and then photographed the external characteristics of the quadrate lobe including its presence, its limits, its seat, its shape, the presence of furrows.Results: Of the 39 livers studied, we noted no cases of absence of the quadrate lobe.However, there were 16 cases of complete presence without fusion or 41.03% of cases and 23 cases of presence with fusion or 58.97%.We noticed the absence of total fusion of the lobe with the right lobe and 6 cases of fused quadrate lobe with both the left and right lobe.We noticed the predominance of the rectangular shape with 68% of cases, followed by the ovoid shape with 25% of cases.The square shape was observed in only two cases.Six cases (15%) of fissure of the quadrate lobe are noted of which 4 were transverse and 2 were oblique.No antero-posterior cracks were observed. Conclusion:The quadrate lobe was always present.It is most often partially fused with the right lobe, or the left lobe or both.Complete fusions are done with the left lobe.The quadrate lobe does not reflect its name in its shape which is rectangular in the majority of cases.The presence of fissures in its surface is not uncommon.These data contribute to the improvement of anatomical knowledge of the quadrate lobe in the management of liver pathologies.
