The seminal vesicles are difficult to evaluate clinically. Transrectal ultrasound (TRUS) has only recently allowed adequate assessment of these structures and their disorders. As the use of TRUS increases, radiologists must familiarize themselves with diseases of the seminal vesicles and the normal and abnormal appearance at ultrasound. This paper presents four cases illustrating the uncommon disorders that TRUS can demonstrate in the seminal vesicles: ectopic ureter entering the seminal vesicle, symmetrically enlarged seminal vesicles with male infertility, a pelvic arteriovenous malformation mimicking a seminal vesicle cyst, and tuberculosis. In two patients, TRUS was used to guide needle aspiration of seminal vesicle contents safely and to inject contrast for radiography.
精囊在临床上很难评估。经直肠超声（TRUS）直到最近才能够对这些结构及其疾病进行充分评估。随着TRUS使用的增加，放射科医生必须熟悉精囊疾病以及超声下的正常和异常表现。本文介绍了四个病例，说明了TRUS可显示的精囊罕见疾病：异位输尿管进入精囊、伴有男性不育的对称性增大的精囊、酷似精囊囊肿的盆腔动静脉畸形以及结核病。在两名患者中，TRUS被用于安全地引导针吸精囊内容物并注入造影剂进行影像学检查。
