    Abstract:
    BACKGROUND: Although spinal infections have been reported following dental procedures, development of a spinal infection attributed to poor dentition without a history of a dental procedure in an immunocompetent adult has not been previously reported. Here we provide a case report of a multilevel lumbar spine infection that developed in an immunocompetent adult with poor dentition. CASE PRESENTATION: A 63-year-old white male man with past medical history of hypertension presented to a hospital emergency department with a 4-month history of progressively worsening low back pain. A musculoskeletal examination demonstrated diffuse tenderness in his lumbar spine area and the results of a neurological examination were within normal limits. Computed tomography and magnetic resonance imaging of his lumbar spine demonstrated a prevertebral and presacral fluid collection ventral to the L4 to L5 and L5 to S1 interspaces. Blood cultures grew pan-sensitive Streptococcus intermedius in four of four bottles within 45 hours. Using computed tomography guidance, three core biopsies of the L4 to L5 interspace were taken and subsequent cultures were positive for Streptococcus intermedius. He reported that his last episode of dental care occurred more than 20 years ago and a dental panoramic radiograph demonstrated significant necrotic dentition. Ten teeth were extracted and the necrotic dentition was assumed to be the most likely source of infection. On hospital dismissal, he received a 12-week course of intravenously administered ceftriaxone followed by an 8-week course of orally administered cefadroxil pending repeat imaging. CONCLUSIONS: This case report demonstrates the importance of determining the source of infection in a patient with a spontaneous spinal infection. Even in the absence of a recent dental procedure, dentition should be considered a possible source of infection in an immunocompetent patient who presents with a spontaneous spinal infection.
