Abstract
Several case reports and studies have described the positron emission tomographic (PET) findings of intracranial tuberculomas and bacterial brain abscesses. However, to our knowledge, the PET pattern of a tuberculous brain abscess has not been previously described. We report the case of a diabetic heavy drinker with a left parietal tuberculous abscess. 18F-fluoro-2-deoxyglucose (FDG)-PET scans showed intense FDG uptake at the abscess periphery, where contrast enhancement was observed on a magnetic resonance image. FDG uptake was reduced within the abscess cavity and in the adjacent cerebral cortex. The possibility of a tuberculous brain abscess should be considered when FDG accumulates at the periphery of a ring-enhancing lesion in a chronically ill or immunocompromised patient.
