Congenital lesions of the seminal vesicles are rare. Zinner syndrome is an uncommon congenital syndrome comprising seminal vesicle cysts with unilateral renal agenesis and ipsilateral ejaculatory duct obstruction. Patients can be asymptomatic or present with symptoms, usually between the ages of 11 and 40 years. The clinical presentation is nonspecific but abdominal pain, pelvic pain, urinary irritation symptoms, and infertility have been reported previously. Diagnosis is mainly through computed tomography and magnetic resonance imaging. The management strategy for Zinner syndrome depends on the severity of symptoms and the size of the cysts. Small and asymptomatic cysts are managed conservatively. Surgical management can proceed through open, laparoscopic, or robotic approaches. Herein, we present a rare case of Zinner syndrome managed at a private multispeciality hospital in Kigali, Rwanda.
