An 83-year-old man was referred with a right lung mass on dynamic chest computed tomography (CT). F-18 fluoro-deoxy-glucose positron emission tomography (FDG PET)/CT showed intense FDG uptake in the right lung mass and bilateral hypermetabolic mediastinal lymph nodes. CT-guided biopsy of the right lung mass revealed metastatic adenocarcinoma from the colon, but a colon cancer lesion was not detected by dynamic abdominal CT and colonoscopy.
一位 83 岁男性因动态胸部计算机断层扫描(CT)发现右肺肿块而就诊。F-18 氟代脱氧葡萄糖正电子发射断层扫描(FDG PET)/CT 显示右肺肿块和双侧高代谢性纵隔淋巴结摄取 FDG 明显增加。CT 引导下右肺肿块活检显示来自结肠的转移性腺癌,但动态腹部 CT 和结肠镜检查均未发现结肠癌病灶。
