title: Unusual retrovesical masses in men.
abstract: Retrovesical masses in men not related to prostatic carcinoma or hyperplasia is an uncommon pathology. Rare masses or unusual manifestations of those common diseases are a diagnostic dilemma. We review our experience in three unusual retrovesical masses in men: carcinosarcoma filling a giant bladder diverticulum; cystic prostatic carcinoma; and acquired cystic dilatation of the seminal vesicle associated with a prostatic carcinoma that obstructed and invaded the vesicle. We report the imaging findings and review the literature. In our experience, the imaging findings are usually not specific for doing a precise diagnosis and biopsy procedures are necessary.
