Ga prostate-specific membrane antigen (PSMA) PET/CT is used in the staging, evaluation of biochemical recurrence, and response assessment of patients with prostate cancer. In addition to the PSMA-expressing prostate cancer cells, Ga-PSMA binds to the neovasculaature of various other solid tumors and benign lesions. We report a case of a 72-year-old man with recently diagnosed adenocarcinoma of prostate, incidentally found to have pleomorphic sarcoma on the staging Ga-PSMA PET/CT.
前列腺特异性膜抗原（PSMA）PET/CT 用于前列腺癌患者的分期、生化复发评估和反应评估。除了表达 PSMA 的前列腺癌细胞外，Ga-PSMA 还与各种其他实体肿瘤和良性病变的新生血管结合。我们报告了一例 72 岁男性，最近诊断为前列腺腺癌，在分期 Ga-PSMA PET/CT 上意外发现多形性肉瘤。
