Usefulness of magnetic resonance imaging for congenital prepubic fistula.
Congenital prepubic fistula is a rare congenital anomaly. Complete removal of the fistular tract remains challenging because of the complicated course. Although conventional fistulography has been used widely as a diagnostic tool for congenital prepubic fistula, more detailed information such as accurate localization of the fistular end or relative position to the urinary tract cannot be preoperatively obtained because the conventional contrast studies have insufficient capability. In this article, we reported the complete removal of congenital prepubic fistula based on preoperative magnetic resonance imaging findings, especially T2-weighted imaging. Magnetic resonance imaging clearly displayed not only the tract of the prepubic fistula originating from a subcutaneous cyst but also the tract extending and ending near the top of the urinary bladder.
