Tuberculomas of the brain in Britain.

Introduction Tuberculomas are granulomas of tuberculous origin which behaves as space-occupying lesions. In some tropical countries they are amongst the commonest of brain tumours, but in this country they have now become exceedingly rare. In one neurosurgical unit in this country only three cases have been seen in the last 21 years, out of a total of 2200 intracranial tumours. These three cases are described and the natural history and clinical features of the condition are discussed. Contrary to what might be expected, it is seldom that a tuberculoma of the brain can be diagnosed pre-operatively in this country, even if the possibility has been considered. Postoperatively, a long-term follow-up is desirable, as relapses of tuberculous infection can occur even after a long interval.
