A Case of Pneumococcal Endocarditis Accompanied by Arthritis and Meningitis

Streptococcus pneumoniae is a common cause of pneumonia. S. pneumoniae also had been a frequent cause of infective endocarditis in the past, but its incidence has markedly decreased after the introduction of effective antibiotics. S. pneumoniae is now a rare cause of this invasive and fatal disease, not to mention S. pneumoniae bacteremia with multiple metastatic infections. We report a 74-year-old woman who presented with arthritis and fever and was diagnosed with infective endocarditis accompanied by meningitis and septic arthritis due to S. pneumoniae without pneumonia. After treatment with antibiotics, the patient recovered without complications. Although S. pneumoniae is a rare cause of infective endocarditis with multiorgan involvement, S. pneumonia should be considered as one of the potential pathogens in such cases.
