Abstract：
The liver is a common location for both primary and secondary cancers of the abdomen. Radiologists become familiar with the typical imaging features of common benign and malignant liver tumors; however, many types of liver tumors are encountered infrequently. Due to the rarity of these lesions, their typical imaging patterns may not be easily recognized, meaning their underlying pathologic features may not be discovered or suggested until an invasive biopsy is performed. In this review article, we discuss multiple hepatic neoplasms that are both unusual and rare. Some have typical imaging patterns, whereas others are non-specific and can only be included in the differential diagnosis. The clinical history and serologic findings are often critical in suggesting these entities; therefore, these are also discussed to familiarize the radiologist with the appropriate clinical setting of each. The article includes an image-rich description of each entity with accompanying figures describing the ultrasonography, computed tomography, and magnetic resonance imaging features of each disease process. Novel therapies and prognosis of several of the diseases are also included in the discussion.
摘要：
肝脏是腹部原发性和继发性癌症的常见位置。放射科医生熟悉常见的良性和恶性肝脏肿瘤的典型影像学特征；然而，许多类型的肝肿瘤很少见。由于这些病变的稀有性,它们的典型成像模式可能不容易识别，这意味着在进行侵入性活检之前，可能不会发现或建议其潜在的病理特征。在这篇评论文章中，我们讨论了罕见和罕见的多发性肝肿瘤。有些有典型的成像模式，而其他是非特异性的，只能包括在鉴别诊断中。临床病史和血清学发现通常是提示这些实体的关键;因此，还讨论了这些内容，以使放射科医生熟悉每种情况的适当临床设置。这篇文章包括每个实体的图像丰富的描述，并附有描述超声检查的附图，计算机断层扫描,每个疾病过程的磁共振成像特征。讨论中还包括了几种疾病的新疗法和预后。
