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 aÂ desmoidÂ tumor. It is important to be aware that many tumors other than prostate carcinoma may also show avid uptake on PSMA PET/CT scan.
