Abstract：
Benign liver lesions are increasingly diagnosed in daily clinical practice due to the growing use of imaging techniques for the study of the abdomen in patients who have non-specific symptoms and do not have an increased risk of hepatic malignancy. They include simple or parasitic hepatic cysts and solid benign tumors which differ widely in terms of prevalence, clinical relevance, symptoms and natural history and often lead to significant clinical problems relating to diagnosis and clinical management. Following the need to have updated guidelines on the management of benign focal liver lesions, the Scientific Societies mainly involved in their management have promoted the drafting of a new dedicated document. This document was drawn up according to the present Italian rules and methodologies necessary to produce clinical, diagnostic, and therapeutic guidelines based on evidence. Here we present the second part of the guideline, concerning the diagnosis and clinical management of hemangioma, focal nodular hyperplasia, and hepatocellular adenoma.
摘要：
由于越来越多地使用成像技术来研究具有非特异性症状且未增加肝脏恶性肿瘤风险的患者的腹部，因此在日常临床实践中越来越多地诊断出良性肝脏病变。它们包括单纯性或寄生性肝囊肿和实体性良性肿瘤，它们的患病率差异很大，临床相关性，症状和自然史，通常导致与诊断和临床管理有关的重大临床问题。根据需要更新良性局灶性肝脏病变的管理指南，主要参与管理的科学协会促进了新的专门文件的起草。本文件是根据目前的意大利规则和方法制定的，诊断,和基于证据的治疗指南。这里我们介绍指南的第二部分，关于血管瘤的诊断和临床治疗，局灶性结节增生,和肝细胞腺瘤。
