Role of magnetic resonance imaging in evaluation of ejaculatory duct in Zinner’s syndrome: case series of five patients and review of the literature

Abstract Background Zinner's syndrome is a mesonephric duct anomaly characterized by unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ejaculatory obstruction due to insult occurred at urogenital tract embryogenesis during the first trimester. In third fourth decades of life, it frequently diagnosed when patients begin be symptomatic, such as lower urinary symptoms, infertility painful ejaculation. Case presentation Herein we illustrate case review including five Zinner’s syndrome, three them complaining from infertility; however, remaining two cases were fertile incidentally diagnosed. Conclusions Radiological investigations play significant role in diagnostic management processes US, CT MRI for detecting agenesis vesicles dilatation, but evaluation can done only transrectal ultrasound; latter may sometimes nonconclusive or intolerable patients, so considered golden modality with its high capability assess male genital which played our series starting detection presence absence well delineation origin nature cyst also size content finally communication between ureteral bud cystic dilatation.
