It's not always varicocele: A strange case of Zinner syndrome.

A 42-year-old man presented with a huge varicocele. The patient was completely asymptomatic and he did not complain of dysuria, perineal discomfort, or ejaculatory pain. During the visit, the mass mimicked a varicocele and during the Valsalva maneuver a reflux was documented by colour Doppler ultrasound and an abdominal ultrasound revealed an agenesis of the right kidney and a 4.5-cm diameter intra-prostatic cyst. An abdominal and pelvis magnetic resonance imaging was then performed, which confirmed the right renal agenesis, with an epididymal enlargement in the body and tail. This is a unique case of Zinner syndrome in which the patient presented with a paratesticular mass mimicking a varicocele.
