118 Possible Causes for Epididymal Mass

  • Varicocele

    Differential Diagnosis of testicular mass: Must-not-miss: Testicular torsion (usually acute, assoc. with pain) Epididymitis (assoc with urethral discharge, erythema, and fever[pedclerk.bsd.uchicago.edu] ) Acute Orchitis (testicular pain, nausea and vomiting, 3-4 days after mumps parotitis) Inguinal hernia Testicular cancer (painless mass, avg age at diagnosis: 32) Benign[pedclerk.bsd.uchicago.edu]

  • Torsion of the Appendices and Epididymis

    As the disease progresses, the sulcus between the epididymis and testis becomes obliterated, and the inflammatory epididymal mass may become contiguous with the testis, producing[barnardhealth.us] […] next to the epididymal head[ultrasoundcases.info] [Lev, 2014; Yang, 2005 ] Findings consistent with torsion of appendix testis : Size of 5 mm or greater May see hyperechogenic mass between epididymal head and upper pole of[pedemmorsels.com]

  • Spermatocele

    Spermatoceles also are believed to form as a result of infection (epididymitis) or trauma.[healthcentral.com] They are more common than epididymal cysts , but can appear very similar.[radiopaedia.org] Usually smooth, soft, and well-circumscribed, spermatoceles are broadly described as scrotal masses.[emedicine.medscape.com]

  • Acute Epididymitis

  • Orchitis and Epididymitis

    Epididymoorchitis requires appropriate antibiotic coverage, as with epididymitis.[aafp.org] This appears as a hypoechoic intratesticular mass devoid of blood flow. The complications of orchitis are abscess formation and ischemia.[radiologyassistant.nl] Follow-up is recommended three to seven days after initial evaluation and initiation of treatment to evaluate for clinical improvement and for the presence of a testicular mass[aafp.org]

  • Neuroectodermal Tumor

  • Orchitis

    On imaging the testis and the epididymal mass both had abundant blood flow, although tumor markers were negative.[ncbi.nlm.nih.gov] In patients who have epididymal and testicular lesions, surgical excision provides the diagnosis.[ncbi.nlm.nih.gov] Epididymoorchitis requires appropriate antibiotic coverage, as with epididymitis.[aafp.org]

  • Primary Ciliary Dyskinesia

    Primary ciliary dyskinesia is an autosomal recessive disorder characterized by chronic upper and lower respiratory tract symptoms. We report the diagnosis of primary ciliary dyskinesia associated with a circular ciliary beat pattern in three siblings. This beat pattern is consistent with a ciliary transposition defect,[…][ncbi.nlm.nih.gov]

  • Mesothelioma

    Left hydrocelectomy was performed and pathological analysis of the epididymal mass revealed a well-differentiated papillary mesothelioma.[ncbi.nlm.nih.gov] Sonography revealed a large left paratesticular mass within the hydrocele. Serum tumor markers were negative.[ncbi.nlm.nih.gov]
