Frequently encountered on abdominal imaging studies, the majority of common benign liver lesions are asymptomatic, confidently diagnosed by imaging, and do not require further workup, follow-up, or treatment. The increasing use of multimodality liver imaging, has allowed the recognition of uncommon evolutions of common benign liver lesions such as size changes, fibrotic regression, and content and vascularization changes, and their complications such as rupture, hemorrhage, thrombosis, extrinsic compression, and malignancy. The purpose of this pictorial review is to describe and illustrate the incidence and diagnostic features of these uncommon evolutions and complications on cross-sectional imaging, mainly on computed tomography and magnetic resonance imaging, with emphasis on those imaging clues which are helpful in the differential diagnosis or indicate the need for treatment.
在腹部影像学研究中经常遇到，大多数常见的良性肝脏病变是无症状的，通过影像学检查可以明确诊断，不需要进一步检查、随访或治疗。多模态肝脏成像的广泛应用，使得人们能够认识到常见良性肝脏病变的不常见演变，如大小变化、纤维化消退以及内容物和血管变化，及其并发症，如破裂、出血、血栓形成、外在压迫和恶性转化。本影像学综述的目的是描述和说明这些不常见的演变和并发症在横断面上的发生率和诊断特征，主要是在计算机断层扫描和磁共振成像上，重点是那些有助于鉴别诊断或提示需要治疗的影像学线索。
