[Seminal Vesicle Abscess Associated with Zinner Syndrome]

We report a case of seminal vesicle abscess associated with Zinner syndrome. A 26-year-old male was admitted to our hospital because of fever and right scrotal swelling. Ultrasound showed an enlarged epididymis and color Doppler ultrasound showed increased vascularity in the epididymis. We diagnosed the case as acute epididymitis and started intravenous antibiotic therapy. Four days after admission, remittent fever persisted and blood culture was positive for Staphylococcus aureus. We performed computed tomography, which showed a right seminal vesicle cyst abscess and right renal agenesis. Our diagnosis was an abscess associated with Zinner syndrome. Transrectal ultrasound-guided transperineal drainage was performed 30 days after admission because seminal vesicle abscess could not be controlled by conservative treatment. Eight days after the procedure, the patient was discharged. One year after the procedure, recurrence of seminal vesicle abscess has not been observed.
