In the brain, tuberculosis can cause tuberculous meningitis, tuberculomas or tuberculous abscess. A tuberculous abscess has a capsule containing pus and acid-fast bacilli. It is similar to a pyogenic abscess. Tuberculomas, on the other hand, do not contain pus; however, they may contain necrotic material. Intracranial tuberculomas are usually an extension of meningitis and are usually multiple, while tuberculous abscess, as in this case, is usually solitary.
