Case report: brain and liver abscesses caused by oral infection with Streptococcus intermedius

Organ abscesses are a rare and life-threatening complication mostly of hematogenously disseminated Infections. We report a case of brain and liver abscesses. Identification of the lesions was made by contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI), respectively. An oral examination comprised an oral focus of infection. Streptococcus intermedius was isolated from oral smear, liver and ventricular drainage, and blood sample. After the commencement of antibiotic therapy, drainage of abscesses and oral rehabilitation, complete recovery was noted. (Oral Surg Oral Med Oral Pathol Oral Radio! Endod 2006;102:e21-e23)
