Children between 6 months to 18 years of age admitted to the teaching hospitals attached to a medical college, who were diagnosed as neurotuberculosis were included in the study. The diagnosis of neurotuberculosis was made according to a predesigned protocol, which included detailed history, physical examination and relevant investigations. Clinical grading at the time of presentation for all patients were done according to the British Medical Council staging. 13 All patients underwent Mantoux

CT scans before and after IV administered contrast material was obtained on a Siemens Somotom ARC computed tomography system which is a modified third generation machine. The CT study was performed according to the departmental protocol specifying sequence and method. Reading of study was done by a consultant radiologist. The CT studies were reported as normal or abnormal. The abnormal CTs were further grouped as: basal enhancement (post contrast), hydrocephalus, granulomata, infarcts, abscess, atrophy and cerebral oedema. Results A total of 45 patients diagnosed as neurotuberculosis were included in the study. CT was abnormal in 41 (91.11%) out of 45 cases and was normal in 4 (8.89%) cases. 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.
