This paper illustrates the spectrum of CT findigns of pulmonary tuberculosis in children and shows theadvantages and complementary nature of CT compared with conventional radiography. Common CT manifestations ofpulmonary tuberculosis in children are mediastinal or hilar lymphadenopathy, air-space consolidation, atelectasisand disseminated nodules. CT is useful in the detection of the disease in equivocal chest radiographs, in thecharacterization of lesions, by demonstrating caseation necrotic areas, calcification and bronchogenic spreadnodules, and in defining the extent of the disease and its complications. This in formation will be helpful in thediagnosis and evaluation of tuberculosis in children.
