Tuberculosis (TB) is a common and often fatal infectious disease caused by various strains of mycobacteria and in India nearly 3-4 million children have tuberculosis and another 94 million are at risk for this disease.
Aim: To compare CT and chest radiography as diagnostic tools for childhood chest tuberculosis in revealing and confirming lymphadenopathy and parenchymal lesions.
Materials and Methods: A prospective observational study was done on 50 patients aged between 2 months and 15 years of age who were clinically suspected to have TB. All 50 patients were evaluated using chest radiograph and CT Thorax and results were compared.
Results: Chest X-ray (CXR) was normal in 6 (12%) patients. CT chest detected mediastinal lymphadenopathy in 3 of them, consolidation in 2 and consolidation with mediastinal lymphadenopathy in 1 patient. The comparision between results of chest radiograph and CT showed statistically significance in detection of mediastinal lymphadenopathy (CT 70% vs CXR 56 %, p = 0.006), pleural effusion (CT 18% vs CXR 16%, p= 0.03) and consolidation (CT 48% vs CXR 36%, p = 0.030).
Conclusion: CT scan chest has advantages over conventional radiographs in diagnosing chest TB in pediatric patients and can detect the disease in patients whose chest radiographs are normal.
