Oncology guidelines currently recommend against performing colonoscopies in the workup of adenocarcinoma of unknown primary unless colonic malignancy is otherwise suggested by clinical signs or symptoms. We present 2 cases of metastatic colonic adenocarcinoma that presented only with neurologic symptoms from vertebral metastasis. Although bony metastases are a rare presentation of colon cancer and colonoscopy is not warranted in the initial workup of adenocarcinoma of unknown primary, we describe these cases as a reminder that bony metastases do not rule out a colon cancer diagnosis.
肿瘤学指南目前建议，在对原发灶不明的腺癌进行检查时，除非临床体征或症状提示存在结肠恶性肿瘤，否则不建议进行结肠镜检查。我们报告2例转移性结肠腺癌病例，这些病例仅表现为椎体转移引起的神经系统症状。尽管骨转移是结肠癌的一种罕见表现，且在原发灶不明的腺癌初始检查中不建议进行结肠镜检查，但我们描述这些病例是为了提醒大家，骨转移并不能排除结肠癌的诊断。
