Management of hepatic granulomatous tuberculosis complicating intravesical BCG for superficial bladder cancer.

Intravesical bacille Calmette-Guérin (BCG) therapy is the most effective treatment for high-risk superficial bladder cancer. Severe systemic complications are rare, but may occur in approximately 1% of cases. We report a severe complication of intravesical BCG: a disseminated Mycobacterium bovis infection with biopsy-proven granulomatous hepatitis in a patient with bladder cancer. We also elaborate on the different management alternatives.
