A 57-year-old man with an adenocarcinoma of the prostate, presented with multiple lymph nodes in the para-aortic and right iliac region on computer tomography (CT). However, since the radiologic images were taken 3 weeks following an urosepsis, the differentiation between inflamed and metastatic lymph nodes is difficult. Thus, an integrated [C] choline positron emission tomography and computer tomography (PET/CT) was performed, showing multiple lymph nodes. The patient was staged as cT3N1M0 and treated with hormonal therapy. The choline PET/CT performed after hormonal treatment showed no more hypermetabolic lymph nodes. This case substantiate the hypothesis that choline PET/CT could be used to evaluate therapy response in prostate cancer patients.
一位 57 岁男性，患有前列腺腺癌，计算机断层扫描（CT）显示其腹主动脉旁和右侧髂区有多个淋巴结。然而，由于影像学图像是在尿路败血症发生后 3 周拍摄的，因此区分炎症性和转移性淋巴结较为困难。因此，进行了整合[C]胆碱正电子发射断层扫描和计算机断层扫描（PET/CT），结果显示多个淋巴结。该患者分期为 cT3N1M0，并接受了激素治疗。激素治疗后进行的胆碱 PET/CT 显示无更多高代谢淋巴结。该病例证实了胆碱 PET/CT 可用于评估前列腺癌患者的治疗反应这一假说。
