Abstract：
Cholangiocarcinoma (CCA) is a rare cancer of the bile duct epithelium, and in the last few decades its incidence rate has been increasing. It is associated with a high mortality rate due to late diagnosis and its aggressive nature. Many risk factors have been identified; some are more common in certain regions than others. CCA can be classified according to its anatomical location or macroscopic growth pattern, the latter being most helpful for imaging interpretation. Clinical features can vary from obstructive-like symptoms to nonspecific symptoms, such as weight loss and malaise. Imaging, specifically MRI/MRCP, is crucial in diagnosing CCA, staging, and treatment planning. Surgery with chemotherapy is the mainstay treatment option, and other palliative treatment options exist for those who have unresectable disease.
摘要：
胆管癌（CCA）是一种罕见的胆管上皮癌，在过去的几十年中，其发病率一直在增加。由于晚期诊断及其侵袭性，它与高死亡率有关。已经确定了许多风险因素；有些在某些地区比其他地区更常见。CCA可以根据其解剖位置或宏观生长模式进行分类，后者对成像解释最有用。临床特征可以从阻塞性症状到非特异性症状，比如减肥和不适。成像,特别是MRI/MRCP，对诊断CCA至关重要，分期,和治疗计划。手术加化疗是主要的治疗选择，和其他姑息性治疗方案存在于那些患有不可切除疾病的人身上。
