68Ga-PSMA Uptake in Anal Fistula on PET/CT Scan

68Ga–prostate-specific membrane antigen (PSMA) PET/CT scan for primary staging discovered increased 68Ga-PSMA uptake in a known anal fistula in a recently diagnosed high-risk prostate cancer patient. The patient had an ongoing history of surgical revisions of complex fistulas in the perianal region, contributing to active inflammation and infection. Recently, reports have demonstrated increased 68Ga-PSMA uptake in different benign inflammatory conditions. This case demonstrates another case of a benign condition associated with increased 68Ga-PSMA uptake.
