Vertebral osteomyelitis (VO) is a relatively rare, but lethal, complication of infective endocarditis (IE). We report two cases who had been given a diagnosis of IE during conservative therapy for VO. A 60-year-old and a 52-year-old men each suffered onset of severe back pain. Magnetic resonance imaging demonstrated osteomyelitis in the lumbar spine. IE was revealed from congestive heart failure and persistent fever, as an unusual complication of VO. A series of echocardiograms demonstrated the progression of valvular lesions and vegetation, despite treatment with antibiotics. We therefore performed surgery. One underwent aortic and mitral valve replacement, and the other underwent aortic valve replacement. VO was treated with long-term antibiotics and good responses were achieved in both patients. The possibility of VO in the lumbar spine should be considered in patients with IE complaining of severe back pain. Appropriate antibiotic therapy over a prolonged period is recommended.
