Focal hepatic atrophy has numerous causes and in many cases is associated with compensatory hypertrophy. We have observed this phenomenon on CT in patients with hepatic neoplasms. Of 12 patients studied, eight had hepatic metastases, two had hepatocellular carcinoma, and two had bile-duct carcinoma. Focal changes in liver morphology (i.e., atrophy with compensatory hypertrophy) were found in five patients at presentation and developed after treatment with systemic or intraarterial chemotherapy in the others. Atrophic changes affected the right lobe in eight patients, the left lobe in three, and part of both lobes in one. Compensatory hypertrophy of part or all of the unaffected liver was found. Ten patients had obstruction of the portal vein branch to the atrophic segment, four of these 10 also had hepatic vein obstruction, and two of these 10 also had bile duct obstruction. Portal vein obstruction appears to be the most important element in the production of focal hepatic atrophy in patients with hepatic neoplasms. After treatment with chemotherapy, tumor regression and atrophy may be associated with compensatory hypertrophy and enlargement of the uninvolved part of the liver. This must not be mistaken for progression of disease.
