Abstract: 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.
