Tuberculosis of the central nervous system accounts for about 5 % of extrapulmonary cases, and meningitis is the most frequent manifestation. The recognition of normal physiological variants and benign false-positive 18F-FDG PET scan findings are crucial for accurate diagnosis. We report an atypical presentation of TB meningitis detected by 67 Ga scan and 18 F-fluorodeoxyglucose (FDG). The FDG-PET scan revealed enhanced uptake of tracer along the posterior portion of the falx cerebri, which is much intense than the gallium uptake in the lesion
