ABSTRACT
A 68-year-old man visited our hospital emergency department with consciousness disturbance. He was diagnosed as bacterial meningitis with septic shock, and initial empirical antibacterial therapy was initiated immediately. Streptococcus pneumoniae. was cultured from the cerebrospinal fluid (CSF), and brain MRIs showed pyogenic ventriculitis. Even though CSF findings improved, he was still in coma and finally died with pneumonia. It is unknown how pyogenic ventriculitis affects the course of bacterial meningitis. We analyzed total 11 inpatients with bacterial meningitis associated with or without the pyogenic ventriculitis, including the present patient, in our hospital. Severity of clinical symptoms and CSF findings might determine the duration of antimicrobial administration, regardless of whether pyogenic ventriculitis existed or not.
