A wide spectrum of pathologies, ranging from inconsequential degenerative and senile changes to clinically significant neoplasms, can affect seminal vesicles (SVs). With rapid rise in use of magnetic resonance imaging for evaluation of prostate in recent years an increasing number of cases of incidental SV pathologies are encountered by radiologists. Despite the high contrast resolution and high spatial resolution offered by multiparametric pelvic MRI, accurate diagnosis of SV processes can at times be challenging. In this article, we review the anatomy and embryology of the SVs and vasa deferentia and then explore the spectrum of diseases affecting them.

从无意义的变性和老年性改变到临床上重要的肿瘤，各种各样的病理学都会影响精囊（SV）。近年来，随着磁共振成像在评估前列腺方面的使用迅速增加，放射科医师遇到了越来越多的偶然SV病理病例。尽管多参数骨盆MRI可以提供高对比度分辨率和高空间分辨率，但对SV过程的准确诊断有时仍具有挑战性。在本文中，我们回顾了SV和vasa deferentia的解剖学和胚胎学，然后探讨了影响它们的疾病谱。
