A 64-year-old man with recently diagnosed prostate adenocarcinoma with a total prostate-specific antigen level of 3.32 ng/mL and Gleason score 4 (3 + 4) was referred for Ga-prostate-specific membrane antigen PET/CT scan for pretreatment staging. Prostate-specific membrane antigen-avid lesion was noted in the right lobe of the prostate gland, corresponding to the known primary lesion. Note was made of another prostate-specific membrane antigen-avid lesion in the right parietal lobe of brain, likely meningioma. MRI scan performed later confirmed the brain lesion to be meningioma.
一位 64 岁男性，诊断为前列腺腺癌，总前列腺特异性抗原水平为 3.32ng/mL，Gleason 评分为 4（3+4），因治疗前分期而行 Ga-前列腺特异性膜抗原 PET/CT 扫描。在前列腺右叶发现前列腺特异性膜抗原阳性病灶，与已知的原发性病变相对应。注意到大脑右顶叶还有另一个前列腺特异性膜抗原阳性病灶，可能是脑膜瘤。随后进行的 MRI 扫描证实脑部病变为脑膜瘤。
