Cerebral Vasculitis Complicating Pneumococcal Meningitis

Area of Science:

• Neurology
• Infectious Diseases

Background:

• Cerebral vasculitis is a rare but severe complication of community-acquired bacterial meningitis.
• Pneumococcal meningitis can lead to parainfectious cerebral vasculitis, resulting in ischemic brain damage.

Purpose of the Study:

• To report a case of pneumococcal meningitis complicated by cerebral vasculitis.
• To highlight potential contributing factors and treatment outcomes.

Main Methods:

• Case report of a 64-year-old woman with pneumococcal meningitis.
• Diagnosis confirmed by cerebral magnetic resonance imaging (MRI).
• Treatment involved delayed addition of high-dose corticosteroids.

Main Results:

• The patient developed parainfectious vasculitis causing ischemic brain damage.
• Clinical and radiological recovery was achieved after corticosteroid administration.
• Potential contributing factors identified: antibiotic underdosing and delayed dexamethasone.

Conclusions:

• Cerebral vasculitis is a cause of neurological deficits in pneumococcal meningitis.
• High-dose steroids can effectively treat this complication.
• Repeat lumbar puncture is advised for patients with deteriorating neurological status despite adequate antibiotics.
