“…12 And they pointed out the typical enhancing pattern and presence of a portal vein branch penetrating the center of the enlarged mass lesion. However, it was not certain whether the authors were reporting adenomatous hyperplasia in the caudate lobe, or marked hypertrophy of the caudate lobe which resembled a tumor.…”

The caudate lobe often exhibits enlargement and nodularity in cases of cirrhosis, which makes differentiation of hepatocellular carcinoma from other masslike lesions of the caudate lobe difficult in cirrhotic patients. A 12×6 cm mass-like enlargement of the caudate lobe was incidentally found by computed tomography in a 38-year-old man suffering from alcoholic liver cirrhosis. Magnetic resonance imaging, liver colloidal scan, and sonoguided liver biopsy were used for the differential diagnosis. A literature review revealed two case reports, all of which (like ours) presented with an enlarged caudate lobe supplied with blood via a branch of the portal vein. Therefore, in cases of giant hyperplasia of the caudate lobe, confirmation of the caudate lobe blood supply and the enhancement pattern might be important for the differentiation.

“…Matsui et al [ 24 ] reported that in patients with cirrhotic liver with aberrant gastric venous drainage, 22%-50% of cases are associated with focal hyperplastic changes at the posterior aspect of segment IV, where the aberrant gastric venous drainage is present[ 24 ] (Figure 11 ). Focal hyperplastic changes such as anomalous portal venous drainage in the caudate lobe have also been reported in cases of cirrhotic liver, with the authors surmising that the etiology of such hyperplastic changes is intimately related to the anomalous portal flow[ 25 , 26 ]. Similarly, focal hyperplasia with anomalous portal flow in the caudate lobe has also been reported in a patient without cirrhosis[ 27 ].…”

Hepatic pseudolesion may occur in contrast-enhanced computed tomography and magnetic resonance imaging due to the unique haemodynamic characteristics of the liver. The concept of hepatic arterial buffer response (HABR) has become mainstream for the understanding of the mechanism of the reciprocal effect between hepatic arterial and portal venous flow. And HABR is thought to be significantly related to the occurrence of the abnormal imaging findings on arterial phase of contrast enhanced images, such as hepatic arterial-portal vein shunt and transient hepatic attenuation difference, which mimic hypervascular tumor and may cause clinical problems. Third inflow to the liver also cause hepatic pseudolesion, and some of the cases may show histopathologic change such as focal hyperplasia, focal fatty liver, and focal sparing of fatty liver, and called pseudotumor. To understand these phenomena might be valuable for interpreting the liver imaging findings.
