Tuberculous Orchitis Following Intravesical Bacille Calmette-Guérin (BCG) Therapy
Abstract
Intravesical therapy with Bacillus Calmette-Guérin (BCG) is a common and effective therapy for bladder carcinoma in situ. The risks associated with intravesical BCG therapy are significant and rare. Accurate diagnosis and prompt initiation of management significantly reduce the morbidity associated with these risks. Here, we discuss a case of BCG orchitis, a rare but treatable complication of intravesical BCG therapy. We present the case of a 55-year-old Puerto Rican incarcerated male who was diagnosed with high-grade Stage T1 urothelial carcinoma after presenting with hematuria, treated with transurethral resection of bladder tumor (TURBT), mitomycin, and intravesical BCG. He presented with left testicular pain and swelling after a failed course of ciprofloxacin with ultrasound findings characteristic of BCG orchitis. The patient received a combination therapy of levofloxacin, rifampin, isoniazid, and ethambutol, which resulted in symptom resolution. Combination therapy was initiated in this patient based on a high index of clinical suspicion, and in the absence of positive cultures. Competing diagnoses were considered and excluded based on the history, imaging findings, and observed response to therapy. As this is an uncommon diagnosis, and as routine infectious workup is often inconclusive, we emphasize that early anti-tuberculous treatment should be considered given a high degree of clinical suspicion based on history and patient presentation.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
