Intravesical bacillus Calmette-Guerin (BCG) is an effective treatment for superficial bladder carcinoma. Serious complications, including disseminated BCG infection, are infrequent. We report a case of granulomatous hepatitis with pneumonitis following intravesical administration of BCG. Cultures for mycobacteria were negative in sputum, bronchoalveolar lavage, liver and blood specimens. All symptoms disappeared within days after steroid therapy. Hypersensitivity reaction should be considered in patients with systemic symptoms after immunotherapy with BCG.
