Background: Odontogenic brain abscess is a rare case primarily caused by normal flora such as Anaerococcus prevotii. Case presentation: A 60-years-old Indonesian female complained of severe left side headaches, hearing loss, a decrease of consciousness, several episodes of nausea and vomiting, and hemiparesis dextra for 5 days. Three months previously, she performed dental operative procedures on the left side of the first and second lower molar and debridement of phlegmon on the left side of the mouth. Head CT scan suggests multiple brain abscesses or high-grade glioma, non-communicating hydrocephalus and suggestive mastoiditis. The patient underwent excision surgery and abscess culture, which resulted in Anaerococcus prevotii. The patient received a metronidazole antibiotic, and on the seventh day, his condition improved. Discussion: Identifying bacterial infection in the brain abscess is crucial for effective treatment. Abscess removal in the brain and antibiotics are treatments for brain abscesses. Conclusion: Odontogenic brain abscess caused by Anaerococcus prevotii infection effectiveness with surgical excision and antibiotics.
