  OBJECTIVE：The objective of this article is to provide a practical review of the conditions other than cirrhosis that can result in diffuse surface nodularity of the liver or portal hypertension. CONCLUSION：Conditions that can mimic cirrhosis on imaging include pseudocirrhosis of treated breast cancer metastases to the liver, fulminant hepatic failure, miliary metastases, sarcoidosis, schistosomiasis, congenital hepatic fibrosis, idiopathic portal hypertension, early primary biliary cirrhosis, chronic Budd-Chiari syndrome, chronic portal vein thrombosis, and nodular regenerative hyperplasia. INTRODUCTION：CT of patients with established cirrhosis shows diffuse surface nodularity of the liver and also may show decreased liver volume with relative hypertrophy of the left and caudate lobes or signs of portal hypertension. When seen at imaging, diffuse hepatic surface nodularity or signs of portal hypertension (i.e., splenomegaly, ascites, or portosystemic varices) are usually due to cirrhosis, but other conditions can also cause these findings. Knowledge of radiologic mimics of cirrhosis is increasingly important because some have been described only recently and because an erroneous diagnosis of cirrhosis in some settings could adversely impact contemporary treatment options. For example, underlying cirrhosis lowers the transplantation status of patients with acute hepatic failure. This article aims to provide a practical and current review of the conditions other than cirrhosis that can result in diffuse hepatic surface nodularity or signs of portal hypertension.
