Otter tail liver is usually asymptomatic. For otter tail liver is an anatomical abnormal development of the liver, manifested as a relatively elongated liver tissue extending from the left lobe of the liver to the left and toward the spleen, which is an anatomical variation that does not have much effect on the liver itself, and has no effect on liver function and other physiological and biochemical functions of the liver, and does not require special treatment. Usually there are no obvious discomfort symptoms, and often when CT or MRI is done, changes in the shape of the liver are found and do not need to be treated. Therefore, there is no need to worry after the discovery of otter tail liver, and no special treatment is needed to bring any discomfort or other diseases.
