title: Tuberculous spondylitis as a complication of intravesical bacillus Calmette-Guerin therapy.
abstract: We report a case of tuberculous spondylitis following intravesical bacillus Calmette-Guerin (BCG) instillation. A 90-year-old male physician living in South Africa received an uncomplicated 6-week course of intravesical BCG (Japanese 172 strain) for high grade superficial bladder carcinoma. He experienced a sudden onset of debilitating lower back pain 16 months following this treatment. A lytic lesion involving the anterior T11 and T12 vertebral bodies was diagnosed and subsequently biopsied. An acid-fast organism was isolated after 3 weeks of incubation and was confirmed through deoxyribonucleic acid probe hybridization as a mycobacterium. High performance liquid chromatography analysis speciated the organism as Mycobacterium bovis BCG, proving that it was acquired through the intravesical therapy.
