An unusual low-abdominal tumor: cystadenoma of the seminal vesicle.

ABSTRACT

Cystadenoma of the seminal vesicle is an extremely rare benign tumor, which to our findings has only been mentioned earlier in seven previous reports. It is a benign and mostly multilocular tumor, thought to originate from embryologic remnants. Preoperative diagnosis is rarely made. Complete extirpation is the correct treatment. We present this first Belgian case with a discussion of imaging techniques, symptomatology, pathology, diagnosis, and treatment.
