Preoperative diagnosis of bilateral tuberculous epididymo-orchitis following intravesical Bacillus Calmette-Guerin therapy for superficial bladder carcinoma.

We report a case of bilateral tuberculous epididymo-orchitis following intravesical Bacillus Calmette-Guerin (BCG) therapy for superficial bladder carcinoma in which the diagnosis was made by ultrasonography prior to surgery. The US findings include heterogeneous enlargement of the epididymis and testis, associated with scrotal-skin thickening and scrotal sinus track. Patients with bladder carcinoma treated with intravesical BCG therapy, the presence of scrotal swelling with scrotal-skin thickening and epididymal involvement suggests tuberculous epididymo-orchitis rather than testicular tumour. It is important to be aware of this rare complication and to be familiar with the ultrasonographic features so that appropriate treatment can be given.
