children who are positive for T.B without having symptoms are diagnosed with latent T.B infection and treated as so . when these children having symptoms of headaches, back pain and vomiting , this raise the suspicion of T.B meningitis or tuberculoma in his head . these symptoms are seen with raised intracranial pressure , which means : high pressure within the fluids inside brain cavities . so a brain CT is needed to role out this high pressure and subsequent spinal tap is needed to confirm the diagnosis of T.B meningitis I hope the child had nothing of the above i hope this helps
