Although brain abscess related to odontogenic origin is relatively well documented, hematogenous spread of brain abscess to oral and maxillofacial regions is rare. We have encountered a case of brain abscess which manifested symptoms in buccal mucosa and submandibular regions. A 69-year-old female was admitted with a history of buccal swelling for 2 weeks. Clinically, parotid gland tumor was most suspected.<BR>However, the histopathological finding by biopsy material revealed phlegmonous inflammation of the oral region. On the rext day of biopsy, the patient suddenly beame drowsy, followed by deep unconsciousness. Computerized tomography demonstrated an area of low density in the right lateral lobe, which suggested brain abscess or glioma. Surgically removed brain tissue was histopathologically diagosed as a brain abscess. Shortly after the operation for brain abscess, buccal swelling gradually became small and finally disappeared. On the past history, the patient had harbored a pulmonary infection about 2 months prior to this. Since pulmonary infection is the most feasible cause of brain abscess, the origin of abscess in this case is attributed to the pulmonary infection. In addition, inflammation in buccal region can be considered to be the spread of brain abscess.
