Left lobe of liver - Lobus hepatis sinister

Description

In dogs, the left lobe of liver (left hepatic lobe) lies almost entirely to the left of the medial plane. 

It forms 30 to 50 % of the total liver mass.

It is subdivided into two sublobes:

  • The left lateral lobe of liver (left lateral hepatic lobe) begins dorsally deeps to the left crus of diaphragm and crosses ventral to the left portion of the tendinous center and ventral to the left portion of the muscular periphery of the diaphragm. The diaphramatic surface of the left lateral lobe of liver ends in a point dorsal to the last sternebra, the lateral border end near the costal arch, the dorsal portion partially caps the body of stomach, the visceral surface lies on the fundus and body of stomach, the central portion is partly covered by the papillary process of the caudate lobe, forming the omental tuber that lies adjacent to the lesser omentum, protruding toward the lesser curvature of stomach. 
  • The left medial hepatic lobe of liver (left medial hepatic lobe) is separate from the lateral lobe of liver by a fissure that begins 1.5 to 3 cm form the most caudoventral portion of the organ that extends to the porta. The left medial hepatic lobe of liver is separate from the quadrate and right medial lobe by a deep fissure, the fissure for round ligament (this fissure contains the round ligament of the liver in the free edge of the falciform ligament) , nearly midsagittal in location, which extends to the porta an nearly to the oesophageal notch.
