Atypical liver malignancies can either be uncommon presentations of commonly encountered liver malignancies or rare tumors infrequently seen in clinical practice and often pose a challenge in diagnostic imaging interpretation. These lesions tend to be highly variable in their imaging appearance and are less well discussed in the literature. Commonly, an inter-disciplinary approach incorporating clinical information, imaging data, and histopathology is needed to reach an accurate diagnosis. The diagnostic radiologist's knowledge of such liver malignancies can aid the clinical team in reaching the correct diagnosis and enabling appropriate management. In this article, we review certain technical considerations and focus on the unusual appearances of common primary and secondary malignant liver lesions, uncommon malignant liver lesions, with emphasis on computed tomography (CT) and magnetic resonance imaging (MRI).
非典型肝脏恶性肿瘤可以是常见肝脏恶性肿瘤的不常见表现，也可以是临床实践中罕见的罕见肿瘤，常给诊断影像学解读带来挑战。这些病变在影像学表现上往往差异很大，在文献中讨论得也较少。通常，需要采用结合临床信息、影像学数据和组织病理学的跨学科方法来做出准确诊断。诊断放射科医生对这些肝脏恶性肿瘤的了解可以帮助临床团队做出正确的诊断，并进行适当的治疗。在本文中，我们将回顾某些技术要点，并重点介绍常见原发性和继发性恶性肝脏病变的不常见表现，强调计算机断层扫描（CT）和磁共振成像（MRI）的应用。
