Objective: The primary objective of this study was to describe the neuroimaging changes of tuberculous meningitis (TBM), and to determine the role of neuroimaging in the diagnosis of TBM. Methods: Between January 2009 and July 2015, we prospectively recruited TBM patients in two hospitals in Malaysia. Neuroimaging was performed and findings were recorded. The control consists of other types of meningo-encephalitis seen over the same period. Results: Fifty four TBM patients were recruited. Leptomeningeal enhancement was seen in 39 (72.2%) patients, commonly at prepontine cistern and interpeduncular fossa. Hydrocephalus was observed in 38 (70.4%) patients, 25 (46.3%) patients had moderate and severe hydrocephalus. Thirty four patients (63.0%) had cerebral infarction. Tuberculoma were seen in 29 (53.7%) patients; 27 (50.0%) patients had classical tuberculoma, 2 (3.7%) patients had “other” type of tuberculoma, 18 (33.3%) patients had ≥5 tuberculoma, and 11 (20.4%) patients had < 5 tuberculoma. Fifteen (37.2%) patients had vasculitis, 6 (11.1%) patients had vasospasm. Close to nine tenth (88.9%) of the patients had ≥1 classical neuroimaging features, 77.8% had ≥ 2 classical imaging features of TBM (basal enhancement, hydrocephalus, basal ganglia / thalamic infarct, classical tuberculoma, and vasculitis/vasospasm). Only 4% with other types of meningitis/encephalitis had ≥1 feature, and 1% had two or more classical TBM neuroimaging features. The sensitivity of the imaging features of the imaging features for diagnosis of TBM was 88.9% and the specificity was 95.6%. Conclusion: The classic imaging features of basal enhancement, hydrocephalus, basal ganglia/thalamic infarct, classic tuberculoma, and vasculitis are sensitive and specific to diagnosis of TBM.

Tuberculous meningitis is an important global medical problem which gives rise to high morbidity and mortality. It is the most severe form of extrapulmonary Mycobacterium tuberculosis. Comprehensive prevention effort, prompt diagnosis and rational treatment are all keys to improving treatment outcomes; yet many unsolved problems remain. On the other hand, the new problems, such as HIV co-infection and drug-resistance are posing important challenges. This review outlines the epidemiology, pathogenesis, diagnosis, management and prognosis of tuberculous meningitis. We mainly focus on research carried out in the recent decades, giving special attention to the work done among the Asian populations

Background: Tuberculous meningitis is a life-threatening manifestation resulting from infection by Mycobacterium tuberculosis, especially in the developing countries. The molecular aspects of pathogenesis of tuberculous meningitis remain poorly understood. We evaluated the correlation of cerebrospinal fluid (CSF) and serum cytokine levels with the clinical outcome of 15 HIV-negative patients with tuberculous meningitis. We also assessed the association of CSF and serum cytokines with neuroimaging of brain findings in the patients. Methods: The prospective longitudinal study was conducted at the University Malaya Medical Centre between 2012 and 2014. Neuroimaging of the brain was performed and the findings of leptomeningeal enhancement, hydrocephalus, tuberculoma, infarcts and vasculopathy were recorded. The CSF and serum specimens were analyzed for IL-1ß, IL-8, IL-10, IL-18, IP-10, IFN-γ, MCP-1, TGF-ß, VEGF, TNF- α, IL-18BPa and MMP-9. The clinical outcome was graded at 3 months based on Modified Rankin scale (mRS). Results: On admission and at one month of anti-tuberculosis treatment, the CSF levels of IL-8, IL-1β, IP-10, IFN-γ and VEGF were elevated in all of the patients. Serum IP-10, MCP-1, IL-1β and IL-8 levels were increased on admission and at one month of anti-tuberculosis treatment. There were statistically significant differences between good and poor outcome (mRS at 3 months) for CSF IFN-γ (p=0.033), CSF IL-10 (p=0.033) and serum VEGF (p=0.033) at one month of treatment. None of the patients showed any association between CSF and serum cytokines on admission and at one month of anti-tuberculosis treatment with neuro-radiological findings. Conclusion: The CSF cytokine levels were not related to TBM disease severity on admission, and changes on MRI/CT scans. CSF levels of IFN-γ and IL-10 at one month of anti-tuberculosis treatment were associated with clinical outcome at 3 months. CSF cytokine levels on admission were not associated with the clinical outcome.
