The role of transrectal ultrasonography in the diagnosis and management of prostatic and seminal vesicle cysts.

Cysts in the region of the prostate and seminal vesicles are interesting because of their differential diagnosis and embryological relevance. We present our experience with 5 cases that include a müllerian duct cyst, diverticulum of the spermatic tract, seminal vesicle cyst and 2 prostatic cysts. Transrectal ultrasonography had a significant role in the diagnostic evaluation of these cysts. Ultrasonographically guided transperineal needle aspiration added significant diagnostic information and might have a therapeutic value. After a review of the literature, we propose an algorithm for the evaluation and management of prostatic and seminal vesicle cysts.
