![]() ![]() Mediastinal lymphadenopathy which is considered as a radiological hallmark of primary TB, could be hard to detect by chest X-ray alone. Relevant radiological features detectable by chest X-ray are: enlarged mediastinal/hilar lymphadenopathy, primary complex of Ranke, pneumonic infiltration, abscess, cavity, calcification, plural effusion and empyema. Since it is difficult to make a diagnosis based on bacteriology, diagnosis of tuberculosis in children strongly relies on radiological findings and tuberculin skin test results. WHO has proposed 4 criteria for diagnosis of tuberculosis in children, of which one should met 3 scores: 1-relevant symptoms (+1), 2-close contact (+2), 3-tuberculin skin test (+1), 4-radiological findings compatible with tuberculosis diagnosis (+1) along with isolation of microorganism from a sample. While high-income countries use sophisticated childhood molecular tests to detect tuberculosis, most developing countries still use a method developed 130 years ago. Non-specific symptoms and signs, difficulties to obtain sufficient sample and pauci-bacillary nature of the disease are the three most important causes. But TB can be hard to diagnose in children. According to WHO and the stop TB partnership, most affected children can be saved with better diagnosis of the condition, greater access to health services and improved coordination of healthcare programs. Although there are many progressions on tuberculosis in adult patients, childhood tuberculosis remains a hidden epidemic in most countries. Children under 3 years of age are at greatest risk for developing tuberculosis however, they are given low priority in most health programs and often go undiagnosed. Tuberculosis (TB) is one of the top 10 causes of death in children worldwide. It seems that thoracic CT scan in children suspected of tuberculosis infection can be limited only to investigation of complications in selected patients.ĭigital Chest X-Ray Thoracic CT Scan Pulmonary tuberculosis Childhood 1. This study proposed that investigation of children suspicious of tuberculosis by digital chest X-ray is still of great value. ![]()
