The caudate lobe becomes enlarged through a compensatory mechanism, being a common finding in chronic liver diseases, and it is often associated with other morphologic abnormalities. While these changes are not pathognomonic, they can represent a piece in the diagnostic puzzle. Clear understanding of the pathophysiological process, corroborated with other key imaging findings, can help radiologists use the caudate lobe size in this differential diagnosis.
