Hilar cholangiocarcinoma (also called Klatskin's tumor) is more common than peripheral cholangiocarcinoma. Sonography, CT, MR imaging, angiography, and cholangiography can suggest the diagnosis, but the major issue of imaging with this tumor is to determine whether the tumor is resectable. The anatomic location of hilar cholangiocarcinoma makes resection difficult, so that surgical exploration of patients with this condition should be undertaken only when preoperative evaluation has shown a potential for curative resection. Preoperative assessment of resectability of hilar cholangiocarcinoma is often extensive, requiring several types of imaging. This pictorial essay reviews the imaging features of hilar cholangiocarcinoma. The role of imaging in the preoperative planning, with specific emphasis on staging extent of disease, including hepatic and vascular involvement, is discussed and illustrated.
肝门部胆管癌（也称为克氏瘤）比周围型胆管癌更常见。超声、CT、磁共振成像、血管造影和胆管造影可提示诊断，但该肿瘤影像学的主要问题是确定肿瘤是否可切除。肝门部胆管癌的解剖位置使切除困难，因此只有在术前评估显示有根治性切除可能时，才应对患有这种疾病的患者进行手术探查。肝门部胆管癌可切除性的术前评估通常范围广泛，需要多种类型的影像学检查。这篇图文并茂的文章回顾了肝门部胆管癌的影像学特征。讨论并举例说明了影像学在术前规划中的作用，特别强调了疾病分期范围，包括肝脏和血管受累情况。
