Here, we report the case of a 54-year-old Asian female who complained of hearing loss as a primary symptom and was diagnosed with pyogenic ventriculitis (PV) derived from Streptococcus agalactiae endocarditis. Both PV and S. agalactiae endocarditis are rare and very severe infections with a high mortality rate. Rapid intensive treatment and surgery were required for successful clinical outcomes %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6568201/
