Abstract

The most common metastatic sites of colorectal cancer are the regional lymph nodes, liver, lungs, and peritoneum. Seminal vesicle metastasis from colon adenocarcinoma is not reported yet; the diagnosis could be challenging. We report a case of seminal vesicle metastasis from a primary ascending colon adenocarcinoma in a 49-year-old man, with elevating carcinoembryonic antigen as the only clinical sign. This also highlights the role of F-FDG PET/CT to detect metastatic adenocarcinoma from colon in the genitourinary system.

摘要

结直肠癌最常见的转移部位是区域淋巴结、肝、肺和腹膜。来自结肠腺癌的精囊转移尚未见报道；诊断具有挑战性。我们报告了一例 49 岁男性原发性升结肠癌精囊转移病例，唯一的临床表现是癌胚抗原升高。这也强调了 F-FDG PET/CT 在检测泌尿生殖系统中来自结肠的转移性腺癌中的作用。
