Streptococcus pneumoniae intracranial abscess and post-infectious vasculitis

Intracranial abscesses are rare complications of Streptococcus pneumoniae infections, and to our knowledge, there have been no case reports of post-infectious vasculitis developing in such patients. Here we describe the case of a 48-year-old post-splenectomy male who developed post-infectious vasculitis following S. pneumoniae otitis media complicated by mastoiditis, osteomyelitis, meningitis, and intracranial abscess. Clinicians ought to be aware of the possible adverse outcomes of invasive S pneumoniae and the limitations of current treatment options.
