Prominent papillary process of the caudate lobe

Discussion:

There is a prominent papillary process of the caudate lobe. The importance of this finding is in not confusing it with a hepatic or pancreatic neoplasm, or a retroperitoneal lymph node. The homogenous appearance, the isodensity to the liver, as well as the smooth edges of transition with the lateral caudate lobe are the keys to making this distinction. In addition, the absence of a dysmorphic liver parenchyma make an exophytic tumor very unlikely.
