A 63-year-old man underwent a (18)F-fluorocholine ((18)F-FCH) PET/CT for staging assessment of a high-risk locally advanced prostate cancer with an equivocal node on conventional workup (Gleason 4 + 5, PSA 11.1; T3b, N(0/1), M(0) on standard staging investigations). (18)F-FCH-avid disease was demonstrated in the prostate and several non-enlarged pelvic nodes. An incidental focus of tracer uptake was reported within the left lobe of the thyroid gland, with subtle enlargement of the left thyroid lobe on the CT component of the study. A diagnosis of diffuse large B-cell lymphoma was confirmed following thyroid ultrasound and cytology.
一位 63 岁男性因高危局部晚期前列腺癌进行了 (18)F-氟胆碱 ((18)F-FCH) PET/CT 分期评估，常规检查发现一个可疑淋巴结（Gleason 4+5，PSA 11.1；标准分期检查显示 T3b，N(0/1)，M(0)）。（18）F-FCH 阳性病变显示在前列腺和几个非肿大的骨盆淋巴结中。研究的 CT 成分报告左叶甲状腺内有放射性示踪剂摄取的偶然焦点，左甲状腺叶有轻微肿大。甲状腺超声和细胞学检查证实诊断为弥漫性大 B 细胞淋巴瘤。
