Zinner Syndrome: A Comprehensive Case Report on Diagnosis and Management

Zinner syndrome, a rare developmental anomaly of the urogenital tract, is a result of disrupted embryonic development of the genitourinary system. With approximately 100 reported cases, this condition is characterized by renal agenesis, ipsilateral seminal vesicle cyst, and vas deferens obstruction or dilation. Most patients remain asymptomatic, making early diagnosis challenging. Various radiologic modalities, including intravenous pyelography, ultrasonography, vasovesiculography, contrast-enhanced computed tomography (CT), and magnetic resonance imaging (MRI), contribute to accurate diagnosis. We present a case of Zinner syndrome, highlighting its rarity and the importance of vigilant imaging for identification. While asymptomatic patients necessitate active follow-up, those with symptomatic presentations may require surgical interventions, such as perineal cyst aspiration, subcutaneous cyst drainage, laparoscopic, or open surgery. Additionally, male patients should be monitored for potential infertility. Our case, involving a 17-year-old asymptomatic individual initially presenting with bilateral pneumonia, underscores the need for ongoing surveillance in managing Zinner syndrome.
