A 44-year-old female patient received proctocolectomy and chemotherapy for a diagnosis of colon cancer 10 years previously and presented here with new onset of cough for 2 months and a progressive increase of her serum CA19-9 level. F-FDG PET/CT imaging revealed a hypermetabolic lesion within the trachea. Immunostaining confirmed that this lesion was a metastatic adenocarcinoma that originated from the patient's initial colon cancer. F-FDG PET/CT enabled localization of unusual endotracheal metastasis and facilitated the development of an appropriate treatment plan.
一位 44 岁女性患者 10 年前因结肠癌接受了直肠结肠切除术和化疗，此次因新出现的咳嗽症状就诊，病程为 2 个月，且血清 CA19-9 水平逐渐升高。F-FDG PET/CT 成像显示气管内存在高代谢病变。免疫组化证实该病变为转移性腺癌，源自患者最初的结肠癌。F-FDG PET/CT 有助于定位不常见的气管内转移，并有助于制定适当的治疗计划。
