Zinner syndrome: A mesonephric duct anomaly with renal agenesis, ipsilateral seminal vesicle cyst, and ejaculatory duct obstruction

Abstract

Anomalies of the mesonephric duct are associated with a combination of renal agenesis/dysgenesis, ejaculatory duct obstruction, and seminal vesical cyst, called Zinner syndrome. We present a case of this rare syndrome in a young male patient, who initially presented with urinary symptoms. The relevant embryology and diagnostic modalities are discussed.
