ABSTRACT

Introduction: Liver is the largest gland in the body mainly situated in the right upper quadrant of the abdomen. Abnormalities of liver are rare. Common abnormalities are irregularities in form, occurrence of one or more accessory lobes, fissures or abnormal ligaments. Rare abnormalities include atrophy, or complete absence of one of the lobes. Although the segmental anatomy of the liver has been extensively researched, very few studies have dealt with the surface variations of the liver. Accessory lobe may be confused with tumour. Accessory fissure may mimic internal trauma at the time of the post-mortem study. Aim: Present study was carried to find out the morphological variations of liver lobes occurring in Mumbai population. Methods & Materials: The materials used for present study comprised of formalin fixed 50 adult livers. Results & conclusion: In the present study we found accessory liver lobes in 3 cadavers i.e. 6 %, atrophy of left lobe in 15 cadavers i.e. 30 %, accessory fissures in 21 cases i.e.42%.There is also abnormal connection between left lobe and quadrate lobe in 14% cases. The findings of study may be helpful to radiologist and surgeons respectively, to avoid possible errors in interpretations and subsequent misdiagnosis, and for planning appropriate surgical approaches.

Keywords: liver lobes, accessory lobes, accessory fissures, atrophy of left lobe, morphology, variations.
