Abstract
Objectives: To study the computed tomography (CT) features of tuberculous meningitis in children. Methods: A total of 45 patients diagnosed with neurotuberculosis were included. Cranial CT scans were done in these patients with and without IV contrast. The CT results were evaluated. Results: CT findings were abnormal in 41 (91.11%) and normal in 4 (8.89%). Basal exudate was the most common finding, seen in 25 (55.55%) cases followed by hydrocephalus in 15 (33.33%) cases. Infarcts were seen in 8 (17.77%), tuberculoma in 6 (13.33%), cerebral oedema in 3 (6.66%) children, cerebral atrophy and cerebral abscess were 1 (2.22%) each. Conclusion: CT is abnormal in the great majority of patients with neurotuberculosis and can aid in the diagnosis. Basal enhancement was the most common finding in our study.

Summary
Tuberculosis is a major global health problem. Worldwide about 8.6 million people developed tuberculosis in 2012, among whom 1.3 million died of the disease.[1] Despite India having a robust antituberculosis programme, one fourth of the global incident tuberculosis cases occur in India annually.[2]. Central nervous system tuberculosis generally mirrors the incidence of tuberculosis in the community. Around 10% of patients who have tuberculosis elsewhere in the body develop neurotuberculosis.[3]. The most important complication of primary tuberculous infection that leads to high mortality and morbidity is neurotuberculosis.[4]
