摘要：

An 84-year-old man underwent 18F-prostate-specific membrane antigen (PSMA) PET/CT for staging of a newly diagnosed prostate adenocarcinoma. PET/CT revealed high 18F-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. © 2022 Wolters Kluwer Health, Inc.
