title: Delayed diagnosis of tuberculous spondylitis masked by concomitant methicillin resistant Staphylococcus aureus infection.
abstract: We present a case of tuberculous spondylitis in which diagnosis was masked by a concomitant pyogenic infection. The patient had undergone percutaneous needle aspiration of an abscess in the cavity of the psoas muscle. Early results from the culture regimen showed isolation of methicillin-resistant Staphylococcus aureus. After eight weeks, mycobacterium tuberculosis was grown at regimen which was cultured at the same site. Initial isolation of pyogenic bacteria, considered to be highly virulent organisms, led to delayed diagnosis and treatment of the tuberculosis.
