Arizona hinshawii osteomyelitis with antecedent enteric fever and sepsis. A case report with a review of the literature.

A case of Arizona osteomyelitis of the spine which occurred 11 months after an episode of gastroenteritis and enteric fever is presented. As close biochemical and antigenic relative of Salmonella, Arizona infection produces a similar clinical course with gastrointestinal manifestations frequently preceding localized infections by several months. The boney lesion in the present case and in three of the four other cases of Arizona osteomyelitis described in the literature was a chronic inflammation which may have a xanthomatous component. The bone destruction caused by Arizona infection is less severe than that of tuberculosis or pyogenic osteomyelitis. Proposed treatment of Arizona osteomyelitis consists of debridement of the localized infection and long term antimicrobial therapy.
