Abstract
Background
The Streptococcus anginosus group is known for its pathogenicity and tendency for abscess formation. The S anginosus group also causes brain abscesses, yet few studies describe this presentation in the pediatric neurology literature. We describe 5 patients with central nervous system infection due to S anginosus group evaluated by child neurologists at the University of Iowa from 2014 to 2020.
Methods
We performed a retrospective case series review of electronic medical records detailing the clinical presentation and course of pediatric patients with S anginosus group–associated central nervous system infection.
Results
We identified 4 males and 1 female (8, 11, 14, 16, and 21 years). Brain imaging showed abscesses in 4 cases and empyema in 1. All underwent neurosurgical intervention and antibiotic treatment. Cultures obtained during the neurosurgical procedure grew S anginosus group (4 cases with Streptococcus intermedius and 1 with Streptococcus constellatus). An 8-year-old boy with a delayed diagnosis died from brain herniation.
Conclusions
Central nervous system infections due to the S anginosus group can be life-threatening. Neuroimaging plays a key role in the early identification of abscesses. Prompt surgical intervention and timely initiation of antibiotics are critical for optimal outcomes.
