Asymptomatic Zinner’s Syndrome Diagnosed during the Sixth Decade of Life: Case Report and Review of the Literature

Seminal vesicle cysts combined with genitourinary anomalies, named since 1914 Zinner's syndrome, are rare. We present a case of asymptomatic 61-year-old married man, with known left kidney agenesia and a previous ultrasound history negative for vesicle cyst since one year before. Digital rectal examination was normal. Diagnostic imaging (both ultrasound and magnetic resonance imaging) showed left seminal vesicle cyst without any intravesical protrusion. In the absence of symptoms, a conservative treatment was decided, with a strict clinical and ultrasonographic follow-up. The diagnosis of Zinner's syndrome was made later, by ultrasound and magnetic resonance imaging, with the development of multilocular seminal vesicle cystic lesion, with a rapid onset (within one year). This malformation should be considered in the differential diagnosis of a pelvic cyst in male patients with renal agenesis.
