Nonmalignant liver masses are increasingly being recognized with the widespread use of imaging modalities such as ultrasonography, computed tomography, and magnetic resonance imaging. The majority of these lesions are detected incidentally in asymptomatic patients. Based on the radiologic appearance, benign lesions can be categorized as solid or cystic, single or multiple, hypervascular or hypovascular. Based on histologic characteristics, they are classified as of hepatocellular, biliary, or mesenchymal origin. In the majority of patients, a proper diagnosis can be made based on these characteristics on imaging modalities alone. An invasive approach is seldom required. This review discusses the various characteristics of the most common benign liver lesions and recommends a practical approach.
随着超声、计算机断层扫描和磁共振成像等成像方式的广泛应用，非恶性肝脏肿块越来越多地被发现。这些病变大多数是在无症状患者中偶然发现的。根据放射学表现，良性病变可分为实性或囊性、单发或多发、高血供或低血供。根据组织学特征，它们被分类为肝细胞起源、胆管起源或间叶组织起源。在大多数患者中，仅根据这些成像方式的特征就能做出正确诊断。很少需要采用侵入性方法。本综述讨论了最常见的良性肝脏病变的各种特征，并推荐了一种实用的方法。
