Periurethral Teflon injections are being used increasingly for the treatment of urinary incontinence after radical prostatectomy. We report a case of a man who developed increasing obstructive urinary symptoms and stress incontinence following radical retropubic prostatectomy. Six months earlier, he had undergone periurethral Teflon injections. On transrectal ultrasound and magnetic resonance imaging, a 3.2‐cm cystic lesion was noted at the prostatic bed near the bladder neck where the Teflon had been injected. Ultrasound‐guided transperineal fine‐needle aspiration of the cyst yielded a specimen with numerous birefringent crystalline Teflon particles. Although previous reports have described granulomatous tissue reaction, no multinucleated giant cells were present to suggest granuloma formation. To our knowledge, this is the first reported case of Teflon cyst formation following periurethral Teflon injections. The patient's history, imaging studies, cytopathology, and review of the literature are presented in this report. © 1992 Wiley‐Liss, Inc.
