Abstract

Insights

This study reports the fourth known case of a Streptococcus salivarius brain abscess, the first intra-parenchymal one, and the first following an anti-SARS-CoV-2 vaccine. This rare brain abscess case highlights potential vaccine side effects.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Vaccinology

Background:

  • Assessing brain abscess incidence during the COVID-19 pandemic is challenging.
  • Rare cases of brain abscesses have been linked to COVID-19 infection and anti-SARS-CoV-2 vaccines.
  • Streptococcus salivarius is an uncommon cause of brain abscesses.

Observation:

  • A 63-year-old man developed neurological symptoms after receiving a third anti-SARS-CoV-2 vaccine dose.
  • Symptoms included left hemiparesis, facial palsy, vertigo, and balance issues.
  • Brain imaging revealed a right temporo-parietal lesion, and biopsy confirmed a Streptococcus salivarius brain abscess.

Findings:

  • This is the fourth reported case of a Streptococcus salivarius brain abscess globally.
  • It is the first reported intra-parenchymal and supra-tentorial Streptococcus salivarius brain abscess.
  • This case represents the first instance of such an abscess occurring after anti-SARS-CoV-2 vaccination.

Implications:

  • The case highlights a rare potential side effect of anti-SARS-CoV-2 vaccines.
  • Further research is needed to understand the potential link between vaccination and sepsis-induced immunodepression.
  • This finding contributes to the understanding of rare neurological complications post-vaccination.
