Congenital prepubic sinus is a rare congenital anomaly situated in the midline of the lower abdomen. We report a case of congenital prepubic sinus, closely associated with a urachal remnant. Preoperative magnetic resonance imaging showed clearly that the sinus tracked the urachus caudally. This finding supports the theory that the anomaly is caused by abnormal remnant tissue originating from the cloacal membrane, which tracks the allantois duct caudally along with fetal longitudinal growth.
先天性耻骨前窦是一种罕见的先天性异常，位于下腹部中线。我们报告一例先天性耻骨前窦，与脐尿管残迹密切相关。术前磁共振成像清楚地显示窦道沿着脐尿管向尾部追踪。这一发现支持了这样一种理论，即异常是由源自泄殖腔膜的异常残留组织引起的，该组织随着胎儿纵向生长沿着尿囊管向尾部追踪。
