Streptococcus pneumoniae-Related Infective Endocarditis Complicated by Development of Psoas and Epidural Abscesses

Streptococcus pneumoniae (S. pneumoniae), a gram-positive bacterium in the upper respiratory tract, can cause pneumonia, meningitis, and bloodstream infections. S. pneumoniae septicemia may lead to cardiac valve seeding, increasing the risk of epidural and psoas abscesses. Understanding its pathology is crucial for improving early detection and intervention. A 55-year-old male patient presented with fever, acute disorientation, and confusion. Initial broad-spectrum antibiotics were adjusted following positive blood cultures for S. pneumoniae. While meningitis was the primary concern, further imaging revealed mitral valve vegetation, an epidural abscess (L2-L4), osteomyelitis, and a psoas abscess. Due to an unsuccessful lumbar puncture, CSF analysis was not obtained. The patient received IV Ceftriaxone and Vancomycin and underwent a successful laminectomy, completing six weeks of antibiotics. This case highlights the severe complications of S. pneumoniae infective endocarditis, particularly its hematogenous spread leading to an epidural abscess. While cardiac valve seeding is well-documented, its role in epidural abscess formation is often overlooked. Given the diagnostic challenges of spinal epidural abscesses due to their resemblance to meningitis, accurate and timely diagnostics are critical for optimizing treatment and preventing deterioration.
