Abstract
An unusual anatomical variation known as "beaver tail liver" occurs when the liver's left lobe spreads laterally until it touches the spleen. It is also known as a sliver liver, saber-shaped liver, or flax-like liver. We are talking about a 34-year-old man, a chronic alcoholic in this case, who had complaints of upper abdominal pain, persistent vomiting, and abdominal palpation elicited tenderness in the upper abdomen. Also, he had hepatosplenomegaly. On further investigation, he was diagnosed with alcoholic hepatitis, and on computed tomography, there was enlargement of the left lobe of the liver, which was beaver tail liver. This case report aimed to present a detailed account of a patient presenting with upper abdominal pain and clinical suspicion of acute pancreatitis. On imaging, there was a beaver tail liver. This unusual morphology can be an incidental finding during imaging studies or surgical procedures, often posing diagnostic challenges and considerations for clinicians.
