A 60-year-old man was admitted to our hospital after being found at his home in a comatose state. Cerebrospinal fluid and blood cultures were positive for Streptococcus pneumoniae. Brain magnetic resonance imaging (MRI) revealed sinusitis in the sphenoid sinus. Computed tomography demonstrated the presence of multiple air pockets in the basilar cistern, and we diagnosed pneumococcal meningitis complicated with pneumocephalus. Multiple cerebral infarctions were found on brain MRI after admission. In this case, pneumocephalus was secondary to pneumococcal meningitis due to sinusitis on admission, and multiple cerebral infarctions after admission. We demonstrated that early diagnosis is required for the successful treatment of pneumococcal meningitis.
