Abstract
Central nervous system tuberculosis (TB) is the most severe extra pulmonary TB having a high mortality and morbidity. OBJECTIVE: To study the various clinical, biochemical, and radiological spectrum of intracranial TB. MATERIALS AND METHOD: Ninety-three patients were enrolled in this prospective study after ethical clearance and consent from August 2013 to May 2015. The entire clinical course with complications and predictors of mortality were assessed. RESULTS: 36 females (38.7%) and 57 males (61.3%) were included whose mean age of presentation was 32.3±17.05 years. Alcohol was the most common risk factor seen in 19.4%. Headache (90.3%) was the most common symptom. Co-infection with human immunodeficiency virus, cryptococcal, and toxoplasmosis were seen in 11, 3, and 2 patients, respectively. Cerebrospinal fluid analysis showed acid-fast bacilli in 1 patient; polymerase chain reaction for TB and BACTEC was positive in one and three patients, respectively. Neuroimaging showed basal exudates (21.7%), tuberculoma (28.6%), brain edema (27%), hydrocephalus (32.9%), infarct (21%), and abscess (2.9%). Complications were noted such as brain edema (24.7%), vasculitis (26.9%), hydrocephalus (17.2%), hyponatremia (11.8%), drug-induced hepatitis (4.3%), and drug rash in 5 patients (5.4%). A total of 25 patients (26.9%) died and 38 patients (40.9%) developed neurological sequelae like hemiparesis, paraparesis, visual loss, and hearing loss. Logistic regression showed that a Glasgow scale of <10, British Medical Research Council stage 3, and vasculitis were associated with poor outcome. CONCLUSION: Lack of sensitive diagnostic method and criteria makes central nervous system TB a challenge where early diagnosis and prompt management is required.
