摘　　要：在肝硬化背景下,尤其是酒精性肝硬化中,发现一种组织学近似于肝脏局灶性结节性增生(FNH)的局灶性病变,即局灶性结节增生样结节(FNH-LNs)。影像学可表现为动脉相高增强,门脉或延迟相低增强,临床上易误诊为肝细胞癌。本文通过复习国内外相关文献,重点对FNH-LNs的病因、临床病理特征和影像学表现进行综述,以便更好地鉴别FNH-LNs与肝细胞癌,指导治疗方式的选择。A kind of focal lesions called focal nodular hyperplasia-like nodules(FNH-LNs)was found in liver cirrhosis,especially in alcoholic cirrhosis,which is similar to focal nodular hyperplasia in histology.The imaging features of FNH-LNs show hyperenhancement in arterial phase,hypoenhancement in portal venous phase or delayed phase.FNH-LNs are easily misdiagnosed as hepatocellular carcinoma(HCC).With reviewing the relating articles in China and abroad,this article summarizes the etiology,clinicopathological features and imaging manifestations of FNH-LNs,so as to distinguish FNH-LNs and HCC in cirrhosis and guide selection of treatment.
