Genitourinary tract tuberculosis is a specific chronic granulomatous infection. However, epididymal tuberculosis presented as a huge scrotal mass is uncommon. We report one case of epididymal tuberculosis that was noted 5 months after the prostate biopsy and was managed with unilateral simple epidymo-orchiectomy. Antituberculous drugs have been given as the medical treatment of tuberculosis postoperatively. Urinalysis became normalized and the scrotal ultrasonography showed normal left epididymis and testicle at 6-month follow up.
