The role of radiology in diagnosis of Zinner syndrome in a young man with scrotal pain

Abstract

Zinner Syndrome is a rare congenital anomaly. It is considered a rare cause of male infertility and can cause a range of clinical manifestations that may lead to significant morbidity. The diagnosis of Zinner Syndrome requires a high index of suspicion, combined with a detailed clinical evaluation and imaging studies. Ultrasonography, computed tomography, and MRI are the imaging modalities of choice for the diagnosis of this condition. Radiological evaluation also plays a crucial role in the management of Zinner Syndrome. In symptomatic cases, surgical intervention may be necessary, and radiology is essential for surgical planning and postoperative monitoring. In this case report, we describe an uncommon case of a 35-year-old patient with vague scrotal pain and discuss the clinical presentation, diagnosis, and management of this rare condition. Prompt and accurate diagnosis is important to prevent the potential morbidity associated with this condition, such as recurrent epididymitis, urinary tract infections, and infertility.
