A 52-year-old unvaccinated and splenectomized man presented with fever, altered sensorium, bilateral flank pain and chest discomfort accompanied with paroxysmal atrial fibrillation with a rapid ventricular response. An abdominal computed tomography scan was performed, which revealed a right renal infarct and splenosis. Transthoracic echocardiography was performed, which demonstrated an echodense structure on the mitral valve with mitral regurgitation and a vegetation on the aortic valve with aortic regurgitation. Subsequently, he was found to have pneumococcal infective endocarditis, pneumococcal pneumonia and bacterial meningitis, namely Austrian syndrome. He underwent an early aortic valve and mitral valve repair but still had a poor clinical outcome. Renal infarction has a mortality of approximately 13.2%, which is strongly influenced by the underlying diseases and infectious complications. Medical and surgical treatment initiated in a timely manner is often inadequate. The authors report the first case of Austrian syndrome presenting with renal infarction as a clue to an embolic event associated with infective endocarditis in this study.
