[Sacroiliitis with Erysipelothrix Rhusiopathiae revealing tricuspid endocarditis, the first case reported on the Guiana Shield: clinical case and review of the literature]

We report here an atypical case of acute sacroiliitis caused by Erysipelothrix rhusiopathiae revealing tricuspid endocarditis in a 53-year-old woman without medical history. She was admitted to Cayenne hospital because of intense right hip and thigh pain, associated with fever. A right sacroiliitis was visible on the computed tomography (CT) scan, confirmed on MRI. Transesophageal echocardiography revealed a large mobile tricuspid vegetation. Blood cultures were positive for E. rhusiopathiae. CT scan showed pulmonary alveolar opacities, consistent with septic emboli. Clinical improvement was obtained under ceftriaxone followed by ciprofloxacin for 6 weeks of treatment. We present a review of bone and joint infections caused by E. rhusiopathiae. So far, not a single case has been reported in Latin America.
