Abstract
Deep neck infection, which is serious and potentially life-threatening, has not decreased in frequency despite advances in antibiotics treatment. An 84-year-old woman with poorly controlled diabetes admitted April 25th 2008, for sore throat and a high fever was found in neck computed tomography (CT) to have a deep neck abscess. Despite good postoperative progress, her fever continued. Further careful examinations, in pelvic CT showed a retroperitoneal abscess, which was then treated and controlled with an intravenous antibiotics drip. We suspect that the deep neck infection had spread hematogeneously. Such deep infections in a compromised host must therefore be treated and controlled carefully.
