Abstract

Intravesical bacillus Calmette-Guerin (BCG) instillation has been adopted for the treatment of patients with superficial bladder cancer. Severe adverse events due to local instillation of BCG are uncommon, with an overall rate of serious complications of less than 5%. We report the case of an immunocompetent adult patient with multi-system effects, namely pneumonitis, granulomatous hepatitis and meningitis, who responded well to standard treatment for Mycobacterium bovis. This case highlights the importance of a thorough assessment of this type of patient.

Keywords: Tuberculosis, Mycobacterium bovis, Bladder cancer, Bacillus Calmette-Guerin

Core tip: Intravesical instillation of bacillus Calmette-Guerin (BCG) is a therapeutic option in bladder cancer. Multi-system effects are a rare complication of this procedure, and certain aspects concerning its diagnosis and treatment are unclear. We report the case of a patient who developed effects on multiple organs after intravesical BCG instillations, and we review current knowledge concerning the diagnosis and management of BCG infection.
