Endocarditis Without Risk Factors: Clinical Awareness Is Key.

Infective endocarditis (IE) is a relatively common disease that can manifest as a spectrum of clinical findings. Clinical awareness is key for the diagnosis. We present a case of a 14-year-old adolescent with fever, coughing, skin lesions, lip drooping, and quadrantanopia. Lumbar puncture was unremarkable and a head CT scan showed ischemic lesions. Blood cultures were positive for Staphylococcus aureus. A transesophageal echocardiogram showed a 7 x 7 mm mitral valve vegetation. The diagnosis of IE was made and flucloxacillin was initiated. Clinical suspicion was decisive for diagnosis. This case illustrates a serious and atypical presentation of an already uncommon disease in a patient without known risk factors for IE. While the initial cardiology workup was negative, a high clinical suspicion should always motivate further investigation as the consequences of untreated acute endocarditis are serious and life-threatening.
