Definition

Idiopathic granulomatous epididymitis (IGE) refers to a lesion of the epididymis requiring a period of ≥6 weeks for the duration of symptoms, while others accept a period of 3 months, with no identifiable etiology (Çek et al. 2017).

  • Age

  • Sex

    Male.

  • Site

    Typically unilateral swelling and tenderness of epididymis, usually beginning in the tail and spreading to involve the whole of the epididymis.

  • Treatment

    Some patients who were only medically treated for granulomatous orchitis have recovered, but orchidectomy in cases without a preoperatory diagnosis is the treatment of choice (Morozumi et al. 2018).

  • Outcome

    Patients with a 6 weeks or longer history of discomfort or pain in the epididymis may experience testicular pain generally without any signs of infection; induration involving the spermatic cord could be another symptom.
