[Staphylococcus aureus bacteremia and epidural mass in a patient with tophaceous gout]

We present a case of Staphylococcus aureus septicaemia complicated with endocarditis and spondylodiscitis C2-C3 with compressive epidural mass in a 74-year old patient with a history of gouty arthritis and aortic prosthetic valve. Tophaceous material has been found when surgical decompression of the abscess has been performed. Staphylococcus aureus bacteremia is a serious and common infection with high mortality and complication rate. Amongst those complications, endocarditis is more likely to develop if cardiac prosthetic valve is present. The probability of a metastatic infection may be evaluated by several factors, such as: the time to positivity of blood culture, a community-acquired Staphylococcus aureus bacteremia and the presence of Osler nodes. All were present in our case. In fact, spondylodiscitis C2-C3 with compressive epidural mass was discovered, which was suspected to be an epidural abscess. Epidural abscess is a rare but potentially life-threatening disease that remains often underdiagnosed. Diagnosis is made by imaging and anatomopathological findings. In the case of our patient the finding of tophaceous material raises the issue of the nature of the epidural lesion. Spinal involvement with gout has been described. It can mimic epidural abscesses, most often in an infectious context as it was the case of our patient.
