Abstract：
Focal liver lesions (FLLs) have become an increasingly common finding on abdominal imaging, especially asymptomatic and incidental liver lesions. Gastroenterologists and hepatologists often see these patients in consultation and make recommendations for management of multiple types of liver lesions, including hepatocellular adenoma, focal nodular hyperplasia, hemangioma, and hepatic cystic lesions including polycystic liver disease. Malignancy is important to consider in the differential diagnosis of FLLs, and healthcare providers must be familiar with the diagnosis and management of FLLs. This American College of Gastroenterology practice guideline uses the best evidence available to make diagnosis and management recommendations for the most common FLLs.
摘要：
肝脏局灶性病变（FLL）已成为腹部成像中越来越常见的发现，尤其是无症状和偶然的肝脏病变。胃肠病学家和肝病学家经常在咨询中看到这些患者，并为多种类型的肝脏病变的管理提出建议，包括肝细胞腺瘤，局灶性结节增生,血管瘤,和肝囊性病变，包括多囊性肝病。恶性肿瘤在FLL的鉴别诊断中很重要，医疗保健提供者必须熟悉FLL的诊断和管理。该美国胃肠病学实践指南使用可用的最佳证据为最常见的FLL做出诊断和管理建议。
