An 84-year-old man underwent 18 F-prostate-specific membrane antigen (PSMA) PET/CT for staging of a newly diagnosed prostate adenocarcinoma. PET/CT revealed high 18 F-PSMA uptake in a thigh mass, which was initially suspected for a metastasis. Histopathology revealed a rare entity of spindle cell lipoma, which should be added to the reported list of neoplasms that can show "false-positive" PSMA uptake during evaluation of patients with prostate carcinoma representing a potential interpretative pitfall.
一名84岁男性因新诊断的前列腺腺癌分期接受了18F-前列腺特异性膜抗原（PSMA）PET/CT检查。PET/CT显示大腿肿块处18F-PSMA摄取高，最初怀疑为转移灶。组织病理学显示为梭形细胞脂肪瘤这一罕见实体，在前列腺癌患者评估过程中，它应被添加到可显示“假阳性”PSMA摄取的肿瘤报告列表中，这是一个潜在的解释陷阱。
