Ga-PSMA PET/CT is a new imaging technique that is highly sensitive to metastatic prostate cancer lesions compared with other conventional imaging modalities. We report a case of a 77-year-old man with newly diagnosed prostate carcinoma who had a PSMA PET/CT scan for staging of his disease. An intensely PSMA-avid right pelvic mass was identified abutting the cecum and terminal ileum. Surgical removal and histopathologic examination of this lesion revealed the diagnosis of a desmoid tumor. It is important to be aware that many tumors other than prostate carcinoma may also show avid uptake on PSMA PET/CT scan.
