Ectopic intracaval liver is a very rare congenital abnormality of the liver in which a part of the liver, not contiguous with the liver proper, lies within the inferior vena cava (IVC).
Ectopic hepatic lobes elsewhere have been described rarely as congenital abnormalities, but a location within the IVC has only been reported twice up to 2012 1.
