Transpubic variant of congenital prepubic sinus on magnetic resonance imaging

We report a case of congenital prepubic sinus with this unusual transpubic course in an 18-year-old man. The patient was initially taken to the operating room for excision of a presumed inclusion cyst. At the time of surgery, the collection was found to track proximally and was excised down to the level of the pubic symphysis. Subsequent magnetic resonance (MR) imaging established the diagnosis of congenital prepubic sinus. We describe the different anatomical courses of congenital prepubic sinus, hypotheses of its pathogenesis, and the use of MR imaging in both diagnosis and surgical planning.
