Abstract：
Adenocarcinomas of the distal bile duct are traditionally classified as either pancreatobiliary or intestinal type, with pancreatic adenocarcinoma and cholangiocarcinoma included within the former classification. Cholangiocarcinoma is a rare and deadly malignancy that occurs within three clinically defined regions: intrahepatic, perihilar, and in the distal bile duct. We present a 68-year-old male with a past medical history of human immunodeficiency virus, hepatitis B, hypertension, and hyperlipidemia who presented to the emergency department with a 3-week history of diarrhea, diffuse abdominal pain, malaise, and nausea. Contrast enhanced CT of the abdomen and pelvis revealed a periampullary mass. Endoscopic ultrasound biopsy was performed, with histopathology suggestive of distal cholangiocarcinoma. Endoscopic retrograde cholangiopancreatography was utilized for palliative stent placement until patient received pancreaticoduodenectomy (ie, Whipple procedure). In this case, we highlight the imaging presentation and histopathology of a distal cholangiocarcinoma.
摘要：
传统上，远端胆管腺癌分为胰胆管型或肠型，胰腺腺癌和胆管癌包括在前分类范围内。胆管癌是一种罕见且致命的恶性肿瘤，发生在三个临床定义的区域：肝内，门周,在远端胆管.我们介绍了一名68岁的男性，有人类免疫缺陷病毒的病史，乙型肝炎，高血压,有3周腹泻病史到急诊科就诊的高脂血症，弥漫性腹痛,萎靡不振,和恶心。腹部和骨盆的对比增强CT显示壶腹周围肿块。进行了内窥镜超声活检，组织病理学提示远端胆管癌。内镜逆行胰胆管造影术用于姑息性支架放置，直到患者接受胰十二指肠切除术（即，Whipple程序)。在这种情况下,我们重点介绍了远端胆管癌的影像学表现和组织病理学。
