Hepatic incidental findings often are seen on cross-sectional imaging examinations of the chest, spine, pelvis, or other nondedicated hepatic imaging. Radiologists are tasked with appropriately triaging, which requires further evaluation, even in the setting of an otherwise limited evaluation. This article reviews common benign entities encountered on ultrasound, computed tomography, or magnetic resonance imaging, along with their characteristic imaging features. Imaging features that are suspicious for malignancy or suggest the need for further evaluation also are discussed. Two algorithms are proposed to guide radiologists in their recommendations based on patient risk factors, focal hepatic abnormality size, and available imaging features.
肝脏偶发发现经常在胸部、脊柱、骨盆或其他非专门用于肝脏成像的横断面成像检查中看到。放射科医生的任务是进行适当的分类，即使在其他有限的评估情况下，这也需要进一步评估。本文回顾了在超声、计算机断层扫描或磁共振成像上常见的良性实体，并介绍了其特征性影像学特征。还讨论了提示恶性的影像学特征或提示需要进一步评估的特征。根据患者的危险因素、局灶性肝异常大小和可用的影像学特征，提出了两种算法来指导放射科医生的建议。
