Zinner syndrome: A rare congenital cause of infertility

Abstract

Zinner syndrome is a rare congenital malformation characterized by cystic seminal vesicles and ejaculatory duct obstruction in association with ipsilateral renal agenesis. It appears to be frequently linked to infertility. However, recent advances in imaging, notably MRI, have led to an increase in the diagnosis of this pathology. We describe the case of a 39-year-old patient receiving examination for primary infertility who was identified with Zinner syndrome using ultrasound, CT, and MRI; the patient did not report hemospermia, lower urinary tract symptoms, or perineal pain. Examining the abdomen and external genitalia revealed no abnormalities, and examining the rectal area revealed none at all. Zinner syndrome is a rare congenital condition; we report this case to highlight the etiopathogenesis of this seminal anomaly, its relationship with renal dysgenesis, and to illustrate the imaging of this condition through various diagnostic methods
