Multi-spectral Pattern of Clinical Presentation and the Resultant Outcome in Central Nervous System Tuberculosis: A Single Center Study on the Ubiquitous Pathogen.

Central nervous system (CNS) tuberculosis (TB) is a great medical masquerader having a multi-spectral pattern of clinical presentation, thereby complicating early diagnosis and appropriate management. This review article describes clinical presentation of CNS TB in a group of 47 patients, who were managed in the Nobel Medical College and Teaching Hospital in Biratnagar, Nepal during the last 2 years. We evaluated demographic profile, mode of management, and clinical outcome in these patients. The findings were that intracranial TB was present in 27 (57.5%) patients and the spinal involvement was in 20 (42.5%) patients. The most frequent presentation of the former was TB meningitis with hydrocephalus (55.5%) and that of the latter was Pott's spine with abscess in 50% of cases. TB meningitis with hydrocephalus was the commonest cause of mortality (83.3%) among the patients. CNS TB should be considered in the differential diagnosis in patients presenting with equivocal neurological signs and symptoms, especially in TB endemic regions. It seems prudent to commence early antitubercular therapy for safeguarding such patients from poor neurological outcome as well as mortality it harbingers.
