This prospective study was done over seven years from 1996 to 2003 to investigate the chest computed tomography scan findings along with other radiologic examinations that included chest roentgenography and cranial computed tomography in children with tuberculous meningitis (TBM). Chest roentgenography demonstrated abnormal findings in 32 cases (43%) (hilar adenopathy, 32%; miliary pattern, 18%; bronchopneumonic infiltrate, 24%), while chest computerized tomography was abnormal in 65 cases (88%; p<0.005): mediastinal and hilar lymphadenopathy were present in 46% (p<0.005); miliary pattern, in 23% (p<0.05); and bronchopneumonic infiltrate, in 23% (p<0.05). Cranial computerized tomography was abnormal in 68 cases (92%). Chest computerized tomography scan helps establish the diagnosis of TBM when chest radiography is normal or inconclusive, and it is useful in assessing children with suspected TBM.
