Abstract

A 54-year-old man, a case of prostate cancer, underwent radical prostatectomy and hormone therapy. Elevated prostate-specific antigen level developed 7 years later, but pelvic MRI and bone scan revealed negative results. Radiotherapy was performed under the suspicion of local recurrence but in vain. F-FDG PET/CT performed 1 more year later showed 3 FDG-avid lesions in the right lung and mediastinum. Lung and lymph node metastases were proved with video-assisted thoracoscopic surgery. Bone scan remained negative at that time.

摘要

一名54岁的前列腺癌男性患者接受了前列腺根治术和激素治疗。7年后前列腺特异性抗原水平升高，但盆腔磁共振成像（MRI）和骨扫描结果均为阴性。在怀疑局部复发的情况下进行了放射治疗，但没有效果。1年后进行的氟代脱氧葡萄糖（F-FDG）正电子发射断层扫描/计算机断层扫描（PET/CT）显示右肺和纵隔有3个F-FDG摄取增高的病灶。通过电视辅助胸腔镜手术证实为肺和淋巴结转移。当时骨扫描仍为阴性。
