Abstract

68Ga prostate-specific membrane antigen (PSMA) PET/CT is a relatively new and highly sensitive imaging modality used in staging metastatic prostate cancer. We report a case of a 65-year-old man with newly diagnosed prostate carcinoma who had a PSMA PET/CT scan for staging of his disease. APSMA-avid right pelvicmasswas identified anterior to the sacrum. Surgical removal and histopathological examination of this lesion revealed the diagnosis of schwannoma. It is important to be aware that schwannoma may also show avid uptake on PSMA PET/CT scan and may potentially lead to an incorrect diagnosis of metastatic prostate carcinoma.
