ABSTRACT
Aortic root abscess without any involvement of the aortic valve is extremely rare. This report describes an 11-year-old girl with subperiosteal abscess due to a virulent organism called Panton-Valentine leukocidin-secreting staphylococci. Although her initial transthoracic echocardiogram did not show any cardiac abnormality, she subsequently experienced an aortic root abscess communicating with the left ventricle. The aortic valve was unaffected, and no other cardiac abnormality was detected at any stage. The girl made a complete recovery after surgical intervention for her aortic root abscess, which was increasing in size despite antibiotic therapy. Patients with such illnesses require close monitoring with repeated expert echocardiography and timely intervention.
