Abstract: In recent years, the incidence of focal nodular hyperplasia （FNH） in the liver has gradually increased, and it has become the second most common benign liver disease after hepatic hemangioma. Its course is slow, and complications such as bleeding and rupture are rare, almost no possibility of malignant transformation. The imaging features of typical FNH include central scars and other characteristics. The imaging manifestations of atypical FNH are different and should be diagnosed and differentiated by combining medical history, laboratory examinations, and comprehensive imaging techniques. The surgical indications for FNH should be strictly controlled. The author reviewed the progress of diagnosis and treatment of FNH based on relevant domestic and foreign literature.

Key words: hepatic focal nodular hyperplasia, cause of disease, clinical manifestation, diagnosis, treatment

摘要： 近年来,肝脏局灶性结节性增生（FNH）的发病率逐渐增高,已成为除肝血管瘤外第二常见的肝脏良性病变,其病程缓慢,出血、破裂等并发症少见,几乎无恶变可能。典型性FNH的影像学有中央瘢痕等特征表现,非典型性FNH的影像学表现各有不同,需结合病史、实验室检查及综合多种影像学检查技术加以诊断及鉴别。FNH的手术适应证要严格掌握。笔者结合国内外相关文献,对FNH的诊治进展进行综述。
