Beaver tail liver

Also known as the sliver of liver, beaver tail liver is an anatomic variation of the liver where its left lobe extends laterally to contact and enclose the spleen. Hepatic parenchyma is normal. It may be difficult to distinguish the two organs from each other when both have equal echogenicity or density in ultrasonography and computed tomography. Therefore, it may mimic a splenic trauma or a perisplenic hemorrhage or subcapsular hematoma within the splenic parenchyma.
