Learning objectives  To provide a comprehensive understanding of the embryogenesis and anatomy of the lower male genitourinary tract.To discuss the main different diagnoses and entities that can mimic cysts of the lower genitourinary tract.To emphasize the importance of differentiating these benign lesions from other potential pathologies.
Read more Background  Cysts of the lower male genitourinary tract represent a relatively uncommon entity that is increasingly found and diagnosed through Magnetic Resonance Imaging.Although they are generally benign findings, they can be symptomatic and even the cause of infertility. These lesions may also be associated with various genitourinary abnormalities and can be complicated with episodes of recurrent prostatitis and epididymitis.
Read more Findings and procedure details  The development of the male genitourinary tract is a highly coordinated and complex process.The male reproductive system develops primarily from the differentiation of mesonephric ducts under the influence of testicular hormones and the involution of müllerian derivatives. [fig 1] The Wolffian duct differentiates into key components of the male reproductive system, including the epididymis, vas deferens, seminal vesicles, and ejaculatory ducts.Ultrasonography and magnetic resonance imaging (MRI) are the modality of choice for accurate identification and characterization of male pelvic cysts.MRI is...
Read more Conclusion  Cysts of the lower male genitourinary tract are often incidental findings but can also be clinically relevant and associated with worrisome symptoms and complications.The diagnosis of these lesions can be challenging.Radiologists need to be aware of their location, associations and complications and must recognize the imaging features that are associated with complications or malignancy.
