Variations of the liver are mostly encountered related to its shape, number of lobes and the patterns of ligaments attached Variations related to fissures and vascular supplies are less common. An anatomical variation was observed during routine dissection of a 60 year old male cadaver at Department of Rachana Sharir, Sri Dharmasthala Manjunatheshwara College of Ayurveda and Hospital. The fissure for ligamentum teres was incomplete; which usually extends from inferior border of liver upto a portahepatis. Foramen was created in the inferior surface of liver near to inferior border between quadrate lobe and left lobe of liver . It was passing through the foramina along a tunnel formed by the bridging of hepatic parenchyma in between quadrate lobe and portahepatis and opened at to left border of portahepatis. As a result of parenchymatous bridging, the fissure was absent and so, there was no demarcation of quadrate lobe from the inferior surface of left lobe. The left lobe was extending beyond the left lateral vertical plane. Awareness of such type of anatomical variation can be utilized by anatomists, embryologists, radiologists and surgeons for academic interest, to avoid possible errors in interpretation and subsequent misdiagnosis, and to assist in planning an appropriate surgical approach that is crucial for determining the patient outcome.
