Zinner’s Syndrome: A Confusing Diagnosis in the Face of Chronic Disabling Perineoscrotal Pain in the Young Subject, about a Case

Zinner syndrome is a rare congenital malformation related to an abnormality in the development of the Wolffian duct, the clinical picture of which consists of a triad of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and obstruction of the ejaculatory duct. Chronic perineoscrotal pain may be an indication of the diagnosis of Zinner syndrome to some extent. We report the observation of a 23-year-old patient, married and father of one child, who presented with chronic perineo-scrotal pain revealing on morphological assessment (ultrasound, uroscanner, prostatic MRI) a cystic formation of the seminal vesicle, left renal agenesis with an empty left renal compartment. Given the patient’s refusal of any surgical procedure, treatment consisted of echo-guided puncture of the seminal vesicle cyst bringing back 30 cc of a seroviscous liquid whose analysis revealed spermatozoa, without atypical cells, compatible with a cyst. The clinical evolution was marked by a progressive remission of the scrotal pain with a delay of several months.
