An unusual case of mitral valve infective endocarditis

Pediatric infective endocarditis is unusual and is considered rare when caused by the pathogen Streptococcus pneumoniae. It is, nonetheless, crucial for the pediatrician to be aware of the potential manifestations of this serious disease. We report a case of an immunocompetent child with Turner's syndrome and a bicuspid aortic valve, receiving regular hormonal injections, presenting with pneumococcal endocarditis. Interestingly, the disease was confined to the structurally normal mitral valve and cardiac surgery was necessary.
