Abstract
Periurethral bulking agent injection (or transurethral submucosal injection) is a comparatively less invasive procedure for the treatment of stress urinary incontinence in patients who develop incontinence after radical prostatectomy, and who are more frequently being treated with transurethral submucosal injection. However, as the radiologic findings of bulking agents are not very well known, they can be mistaken for local recurrence in prostate cancer patients who have undergone prostatectomy. Unlike some of the literatures, in which the radiologic features of collagen injections have been reported, the radiologic findings of silicone injections are yet to be determined. Thus, it is our intention to report this case along with the lit-erature review as the authors have experienced an actual case of a silicone injection mistaken as local recurrence.

CT and MR images of a 64-year-old male with prostate cancer treated by radical prostatectomy. A, B. Axial CT images show well-defined, peripheral enhancing nodular lesions around the vesicourethral anastomosis (arrows). C, D. Coronal CT images show well-defined, peripheral enhancing nodular lesions around the vesicourethral anastomosis (arrows). E, F. T2-weighted oblique axial images of prostate MRI show a relatively well-defined nodular lesion with irregular thick walls and internal contents with high signal intensity (arrows).
