Pseudomass of the Bladder Neck after Prostatectomy: Report of Two Cases1

Ethan J. Halpern, MD and Leonard G. Gomella, MD

1 From the Departments of Radiology (E.J.H.) and Urology (L.G.G.), Jefferson Prostate Diagnostic Center, Thomas Jefferson University, 132 S 10th St, Philadelphia, PA 19107-5244. Received March 18, 2002; revision requested May 29; revision received June 13; accepted July 23. Address correspondence to E.J.H. (e-mail: ethan.halpern@mail.tju.edu).

The authors reviewed ultrasonographic (US) images, cystoscopic findings, and biopsy results at the vesicourethral anastomosis in two patients suspected of having local recurrence after radical prostatectomy. A focal, masslike bulge was identified with US at the posterior aspect of the bladder neck, just above the anastomosis. This bulge mimicked the appearance of local recurrence of cancer; however, diagnostic studies, biopsy results, and clinical follow-up failed to demonstrate recurrent cancer. A review of the surgical technique led the authors to conclude that a pseudomass at the vesicourethral anastomosis may result from focal infolding of normal bladder mucosa.
