Seminal vesicle cysts (SVC) and ipsilateral renal agenesis are rare urological congenital anomalies. SVCs may be congenital or acquired. Congenital SVC can be classified as isolated cysts, cysts associated with upper urinary tract anomalies, and cysts associated with autosomal dominant polycystic kidney disease, while acquired SVC is seen most often as secondary to obstruction by benign prostatic hypertrophy, chronic infection, and scarring of seminal vesicle or ejaculatory duct or prior prostate surgery.

In this case, there are multiple left SVCs with the largest one appearing more to the right while it is related to the left seminal vesicle. While the right seminal vesicle is distorted by the large cysts.
