Although the commonest manifestation of Salmonella infection is acute gastroenteritis, infection may spread to the blood-stream may and the illness can present with focal lesions in almost any organ with or without septicemia. We describe here a case of Salmonella typhi infection of a sacroiliac joint that was cured with ciprofloxacin therapy for six weeks. The patient was immunologically normal. Salmonella etiology was not suspected in this case, and the diagnosis was made only after bacterial isolation. Physicians should be aware of this rare manifestation of Salmonella infection, especially in endemic areas.
