This report describes five patients with intracranial tuberculosis (TB
): four with tuberculous meningitis and one with intracranial tubercul
omas. In all cases the diagnosis was confirmed by excision biopsy of a
n enlarged cervical or axillary lymph node. The biopsies showed caseat
ing granulomas and acid fast bacilli, confirming the diagnosis of TB w
ithin 48 h of admission. Lymphnode biopsies may be an effective and pr
actical aid in diagnosing intracranial TB.
