Abstract

Background. Day to day advances in the fields of radiology like sonography and CT need to revive interest in the cadaveric study of morphological features of liver, as the accessory fissures are a potential source of diagnostic errors. Accessory fissures vary from single to multiple over different parts of the liver. Aim. In the present study the morphological features of human liver specimens were evaluated by macroscopic examination and morphometric analysis. Methods. The study was conducted on 58 specimens obtained from cadavers utilized for routine dissection for medical undergraduates from the year 2004 to 2012 in the Anatomy Department of MIMS Medical College. Results. In the present study the livers as described in the established anatomical literature with normal surfaces, fissures, and borders were considered normal. Out of the 58 specimens, 24 were normal without any accessory fissures or lobes and with normal contours. Two specimens were with hypoplastic left lobes. Lingular process of left lobe was observed in only one specimen. Conclusions. Knowledge of the various accessory fissures of liver prevents misdiagnosis of cystic lesions or any pathological lesions of the liver.
