We present the MRI features of a congenital urethroperineal fistula diagnosed in a 12-year-old boy being evaluated after a single urinary tract infection. This diagnosis was initially suggested by voiding cystourethrogram and confirmed by MRI. Imaging revealed an abnormal fluid-filled tract arising from the posterior urethra and tracking to the perineal skin surface that increased in size during micturition. Surgical resection and histopathological evaluation of the abnormal tract confirmed the diagnosis of congenital urethroperineal fistula. MRI played important roles in confirming the diagnosis and assisting surgical planning.
我们介绍了一位 12 岁男孩的病例，他因单次尿路感染就诊，被诊断为先天性尿道会阴瘘。最初通过排尿性膀胱尿道造影检查提示该诊断，后经 MRI 确诊。影像学显示，异常的充满液体的管道从后尿道起始，向会阴皮肤表面延伸，在排尿过程中逐渐增大。对异常管道进行手术切除和组织病理学评估，证实了先天性尿道会阴瘘的诊断。MRI 在确诊和协助手术计划方面发挥了重要作用。
