Tuberculosis epididymo-orchitis following intravesical bacillus Calmette-Guérin immunotherapy

BCG is a well-established treatment for superficial bladder cancer. Although usually well-tolerated, side effects can range from mild cystitis to life-threatening sepsis. Epididymitis is a rare complication of BCG, with only a handful of cases proven to be caused directly by Mycobacterium bovis. We describe one such case, along with radiological findings for this rare complication.
