[Spondylodiscitis as cause of unexplained fever].

An 83-year-old woman was admitted to hospital with complaints of fever, abdominal pain and other complaints suggesting urosepsis. Additional analyses did not reveal the cause of her complaints. After cessation of antibiotic therapy, there was a spontaneous decrease in the infection parameters and she was subsequently discharged. Two and a half months later she was presented in our hospital with low back pain with radiating to the legs. MRI showed signs ofa spondylodiscitis at the level of LIII-LIV existing for some time. Finally, a gram-positive streptococcus infection was found and she was treated with antibiotics for 13 weeks. 6 months later she was free of symptoms. A 57-year-old man was admitted to the intensive care with a double-sided olecranon bursitis and sepsis. An endocarditis caused by Staphylococcus aureus was thought to be the cause of the sepsis and the patient was treated with surgical intervention and antibiotics. Because of persistent sepsis, different CT-scans were performed, and after one and a half months an extensive spondylodiscitis with abscess formation was diagnosed and subsequently treated surgically. A delay in diagnosing spondylodiscitis is the rule rather the exception. The diagnosis should be considered in any patient with localised back pain, especially when accompanied by fever, high ESR, and the presence of risk factors such as high age, diabetes mellitus, immunosuppression, and/or rheumatoid arthritis.
