First case of 18F-FACBC PET/CT-guided salvage retroperitoneal lymph node dissection for disease relapse after radical prostatectomy for prostate cancer and negative 11C-choline PET/CT: new imaging techniques may expand pioneering approaches.We present the first case of salvage retroperitoneal lymph node dissection based on the results of (18)F-FACBC PET/CT performed for a prostate-specific antigen relapse after radical prostatectomy.  The patients underwent (11)C-choline PET/CT, which turned out negative, while (18)F-FACBC PET/CT visualized two lymph node metastases confirmed at pathological examination.
