Ureteral Metastasis From Prostate Cancer: A PSMA PET Pitfall
A 72-year-old man with a history of prostate adenocarcinoma initially managed by radical prostatectomy and salvage radiation therapy underwent resection of a left vas deferens recurrence identified on PSMA PET. Despite an initial response, PSA failed to fall below 3.5 ng/L, prompting re-evaluation with PSMA PET/CT: a left distal hydroureter with presumed physiologic urine activity remains despite diuretic administration. Upon scrutiny of the prior PSMA PET/CT and diagnostic CTs, the distal ureteral uptake matched a subtle circumferential area of enhancing mild ureteral thickening. Pathological review after left uretectomy confirmed metastatic prostate cancer.
