Objective To evaluate the value of Magnetic Resonance Imaging (MRI)for the diagnosis of prostatic utricle and its concomitant diseases in children. Methods MR images of prostatic utricle in 10 children were retrospectively reviewed, non-enhanced scan was underwent in 10 cases, enhanced scan in 6 cases, MRU in 3 cases. Results There was vertical deform shape lesions shown in the median line region behind the bladder in 10 cases, the cryptomere had homogenously low signal on T1W and high signal on T2W, which was similar to that in the bladder. The inner and outer walls of the cryptomere were smooth. The extremitas anterior of the capsular space became sharp, and the high signal with bar-type was interlinked between the cusp of the extremitas anterior and the posterior urethra at the capsular space in 7 cases. The enhancement couldn't be found in capsular space and cystic walls on enhanced images. Its concomitant complication included 5 cases with orchitis, epididymitis and scrotitis,1 case with inflammatory hyperplasia of lymph nodes . There was 1 case with right enorchia and simple cyst, 1 case with the right-kidney-lack concomitant. Conclusion MRI shows characteristic findings in the children with the prostatic utricle, MRI is a useful examination for the diagnosis of prostatic utricle and its concomitant diseases and complication.
