Normal Morphological Variations of Liver Lobes: A Study on Adult Human Cadaveric Liver in Vidarbha Region

Liver is the largest gland in the body. Morphological variations of liver are irregularities in form, occurrence of one or more accessory lobe. Less common abnormality is atrophy, or complete absence of one of the lobes. Aim The present study includes the evaluation of morphological features of human liver specimens by macroscopic examination. Methods The study was conducted on 50 specimens obtained from cadavers utilized for routine dissection for medical undergraduate students in the Anatomy department. Results In the present study the livers as described in the standard anatomical literature with normal surfaces, fissures, and borders were considered normal. Out of 50 specimens studied 56 % of liver were normal.44 % of liver showed one or the other variations. Two specimens were found to be having hypoplastic left lobe whereas lingular process of left lobe was observed in two specimens. The findings may be useful to surgeons and radiologists to avoid possible errors in interpretations and subsequent misdiagnosis, and for planning appropriate surgical approaches.
