Symptomatic intracranial tuberculoma developing during treatment of tuberculosis: a report of 10 patients and review of the literature.

Ten patients with intracranial tuberculomata which developed during treatment for tuberculosis are described. The initial infection was meningeal in five, miliary in three and pulmonary in two and all improved after treatment was started. However 10 days to five months (mean two months) after the start of treatment, new neurological symptoms and/or signs occurred that led to the recognition of intracranial tuberculomata. CT brain scans suggested tuberculomata in all 10 patients; there were several lesions in five and histological confirmation was obtained in three cases. Earlier CT brain scans (six weeks to five months before) were carried out in five patients and in none was a tuberculoma seen. After treatment with anti-tuberculous drugs and control of raised intracranial pressure when present, five patients made a full recovery, three were left with mild neurological deficit and in two it is too early to assess the outcome.
