Answer to Image Quiz

The Beaver Tail Liver, also known as the Silver of liver, is an uncommon anatomical variation in which the left lobe of the liver extends forward, covering the front surface of the spleen [1].This elongation of left lobe of liver is considered morphologically normal and is associated with normal hepatic functions.On imaging, it may be confused with a splenic mass or a splenic hematoma.This condition can also be confused with hepatosplenomegaly in patients where the spleen and the liver come in close contact with each other [2].An even rarer variant of beaver tail lever is also known as the "hiding beaver tail lever".It is seen when the left lobe of the liver lies at an acute angle with spleen and covers the visceral surface of spleen [3].Lastly, this variation may also be mistaken for a fibrous appendix of the liver, which involves a fibrous connective tissue structure that runs over the left lobe of the liver, alongside the left triangular ligament, and connects to the diaphragm [4].Theoretically, this anatomic variant is more prone to injury following abdominal or lower chest trauma [3,5].This case was unique due to an uncommon occurrence; that too in a male, in whom it is very rare.It also highlights the challenges faced by treating doctor in interpreting the diagnosis.Having the knowledge of its existence, and careful evaluation of CT images can help an accurate diagnosis of this condition.
