Abstract

Intrahepatic cholangiocarcinoma (iCCA) represents the second most common liver cancer after hepatocellular carcinoma, accounting for 15% of primary liver neoplasms. Its incidence and mortality rate have been rising during the last years, and total new cases are expected to increase up to 10-fold during the next two or three decades. Considering iCCA's poor prognosis and rapid spread, early diagnosis is still a crucial issue and can be very challenging due to the heterogeneity of tumor presentation at imaging exams and the need to assess a correct differential diagnosis with other liver lesions. Abdominal contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) plays an irreplaceable role in the evaluation of liver masses. iCCA's most typical imaging patterns are well-described, but atypical features are not uncommon at both CT and MRI; on the other hand, contrast-enhanced ultrasound (CEUS) has shown a great diagnostic value, with the interesting advantage of lower costs and no renal toxicity, but there is still no agreement regarding the most accurate contrastographic patterns for iCCA detection. Besides diagnostic accuracy, all these imaging techniques play a pivotal role in the choice of the therapeutic approach and eligibility for surgery, and there is an increasing interest in the specific imaging features which can predict tumor behavior or histologic subtypes. Further prognostic information may also be provided by the extraction of quantitative data through radiomic analysis, creating prognostic multi-parametric models, including clinical and serological parameters. In this review, we aim to summarize the role of contrast-enhanced imaging in the diagnosis and management of iCCA, from the actual issues in the differential diagnosis of liver masses to the newest prognostic implications.

摘要

肝内胆管癌(iCCA)是仅次于肝细胞癌的第二大常见肝癌,占原发性肝脏肿瘤的15%。在过去几年中,其发病率和死亡率一直在上升,预计在未来二三十年内新发病例总数将增加至10倍。鉴于iCCA预后较差且扩散迅速,早期诊断仍然是一个关键问题,由于成像检查中肿瘤表现的异质性以及需要评估与其他肝脏病变的正确鉴别诊断,这可能极具挑战性。腹部对比增强计算机断层扫描(CT)和磁共振成像(MRI)在肝脏肿块评估中发挥着不可替代的作用。iCCA最典型的成像模式已有详细描述,但在CT和MRI上非典型特征也并不少见;另一方面,对比增强超声(CEUS)已显示出巨大的诊断价值,具有成本较低且无肾毒性的有趣优势,但对于iCCA检测最准确的造影模式仍未达成共识。除了诊断准确性外,所有这些成像技术在治疗方法的选择和手术适用性方面都起着关键作用,并且人们对能够预测肿瘤行为或组织学亚型的特定成像特征越来越感兴趣。通过放射组学分析提取定量数据、创建包括临床和血清学参数的预后多参数模型,也可能提供进一步的预后信息。在本综述中,我们旨在总结对比增强成像在iCCA诊断和管理中的作用,从肝脏肿块鉴别诊断中的实际问题到最新的预后意义。
