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 thereby has the same risks of hepatic pathology as the rest of the liver except theoretically in trauma, where it is more prone 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. Hence it may mimic perisplenic haemorrhage or subcapsular haematoma in splenic trauma or a splenic mass.
