Granulomatous epididymo-orchitis, a rare complication of intravesical bacillus Calmette-Guérin therapy for urothelial cancer.

Only a few cases of tuberculous epididymo-orchitis after bacillus Calmette-Guérin (BCG) therapy have been published. This report presents a case of granulomatous epididymo-orchitis after intravesical BCG therapy in a patient presenting with pain and unilateral swelling of the scrotal content. This complication should always be considered when a patient presents with these symptoms after BCG therapy. Isoniazid may be used as a first choice of treatment.
