The widespread use of imaging analyses, either routinely or to evaluate symptomatic patients, has increased the detection of liver lesions (tumors and cysts) in otherwise healthy individuals. Although some of these incidentally discovered masses are malignant, most are benign and must be included in the differential diagnosis. The management of benign hepatic tumors ranges from conservative to aggressive, depending on the nature of the lesions. New imaging modalities, increased experience of radiologists, improved definition of radiologic characteristics, and a better understanding of the clinical features of these lesions have increased the accuracy of diagnoses and reduced the need for invasive diagnostic tests. These advances have led to constant adjustments in management approaches to benign hepatic lesions. We review the biologic and clinical features of some common hepatic lesions, to guide diagnosis and management strategies.
影像学分析的广泛应用，无论是常规使用还是用于评估有症状的患者，都增加了在其他健康个体中检测到肝脏病变（肿瘤和囊肿）的机会。尽管这些偶然发现的肿块中的一些是恶性的，但大多数是良性的，必须包括在鉴别诊断中。良性肝肿瘤的治疗方法从保守到积极不等，具体取决于病变的性质。新的成像方式、放射科医生经验的增加、影像学特征的更好定义以及对这些病变临床特征的更好理解，提高了诊断的准确性并减少了对有创诊断性检查的需求。这些进展导致了对良性肝病变管理方法的不断调整。我们回顾了一些常见肝病变的生物学和临床特征，以指导诊断和管理策略。
