This study describes the use of 18F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET) to detect a chronic odontogenic infection as the possible origin of a brain abscess (BA). A 74-year-old man with esophageal carcinoma was referred to our department to determine the origin of a BA in his oral cavity. He had no acute odontogenic infections. The BA was drained, and bacteria of the Staphylococcus milleri group were detected. Whole body FDG-PET revealed that the only sites of definite uptake of FDG were the esophageal carcinoma and the left upper maxillary region (SUVmax: 4.5). These findings suggested that the BA may have originated from a chronic periodontal infection. Six teeth with progressive chronic periodontal disease were extracted to remove the possible source of BA. These findings excluded the possibility of direct spread of bacteria from the odontogenic infectious lesion to the intracranial cavity. After extraction, there was no relapse of BA.
