Beaver tail liver

Beaver tail liver, also known as a sliver of liver, is a variant of hepatic morphology where an elongated left liver lobe extends laterally to contact and often surround the spleen. It is more common in females. The parenchyma is normal and therefore has the same risks of hepatic pathology as the rest of the liver, except theoretically in trauma, where it is more prone to injury following trauma to the left upper quadrant or lower left chest.

When the liver and spleen have identical density on CT or echogenicity on ultrasound, it may be difficult to differentiate the two organs. Even when they appear different density or echogenicity, it may be mistaken for perisplenic/subcapsular hematoma or a splenic mass 2.
