Acute abdomen revealed Streptococcus gordonii infective endocarditis with systemic embolism

Abstract

Infective endocarditis can result in potentially fatal complications such as heart failure, systemic embolization, mycotic aneurysm and neurological complications. Staphylococci and streptococci are the most common causative agents of infective endocarditis, with Streptococcus gordonii being a rare cause. We present a case of infective endocarditis in a young patient who presented with an acute abdomen 2 months after being diagnosed with cerebrovascular accident. An abdominal computed tomography revealed superior mesenteric artery thrombosis, and infarct in the right kidney and spleen as a result of systemic septic embolism. Echocardiography showed numerous vegetations at the aortic and mitral valves. Infective endocarditis was diagnosed based on echocardiographic findings and positive blood cultures for S. gordonii. He was treated with intravenous benzylpenicillin and was also referred for surgical intervention.
