Abstract：
Prostatic utricle cyst is an embryological remnant of the Muller duct system, resulting from an incomplete regression of these structures during embryological development. Most of the time such congenital alteration is asymptomatic, but may sometimes present with various signs and symptoms, from urinary tract infections to episodes of haematospermia in a small percentage of cases.
We reported the case of a 42-years-old man who suffered from recurrent episodes of haematospermia for about 20 years; the instrumental examinations, first of all TRUS and then MRI evaluation, demonstrated the presence of a cystic formation, located in the posterior median site of the prostate closely to the prostatic urethra.
The cytological examination on the liquid taken by transperineal US-guided fine-needle aspiration, confirmed the presence of seminal fluid and normal prostatic tissue consistent with the diagnostic hypothesis of prostatic utricle cyst.
It\'s important to recognize the imaging characteristics of the prostatic utricle cyst since it may be one of the possible benign causes of hematospermia in the young adult subject.

摘要：
前列腺囊囊肿是Muller导管系统的胚胎学残余，由于胚胎发育过程中这些结构的不完全回归。大多数时候这种先天性改变是无症状的，但有时可能会出现各种体征和症状，从尿路感染到血精症发作的一小部分病例。
我们报道了一例42岁的男子，他反复发作血精症约20年；仪器检查，首先是TRUS，然后是MRI评估，证明了囊性形成的存在，位于前列腺的后正中部位，靠近前列腺尿道。
经会阴超声引导细针穿刺取液的细胞学检查，证实精液和正常前列腺组织的存在符合前列腺囊囊肿的诊断假设。
认识前列腺囊囊肿的影像学特征很重要，因为它可能是年轻成年受试者血精的可能良性原因之一。
