Abstract
Background
Gallium-68 citrate is an emerging diagnostic tool for the evaluation of infections. Its performance in brain infections is unknown. The available diagnostics for central nervous system tuberculosis are imprecise.
Case presentation
We report a patient with large, active, enhancing, microbiologically confirmed tuberculomas in the right frontal lobe, who underwent Gallium-68 PET CT. It did not show any tracer uptake in the tuberculous lesions.
Conclusions
We report caution in using Ga-68 PET CT for CNS TB and discuss the potential reasons for this observation.
