“…Our findings contrast with two studies in adults in which CXR screening failed to identify any cases of active TB among asymptomatic healthcare workers 7 8. However, an important difference between these studies in adults and our study is that our patients had a TST/IGRA as a result of identified risk factors for TB, whereas the previous studies screened low-risk populations.…”

“…Features suggestive of active TB (defined as cavitation, consolidation, pleural effusion and miliary disease) or prior TB (defined as pleural thickening, fibrous scarring, calcified lymph node and calcified granuloma) were documented 7. Non-calcified hilar lymphadenopathy was documented as a separate category.…”

“…Recent studies in adults, however, question the need for a CXR in TST/IGRA-positive individuals who are asymptomatic 7 8. The diagnostic yield of a CXR in this setting has not been specifically investigated in children.…”

“…By our observation fibrocalcified lesions should be evaluated for active TB specifically in this era which the prevalence of patients with active TB presented with atypical manifestations is increasing (24). Besides, patients with these manifestations are ignored even though they are a reservoir for distributing M. tuberculosis (25). So we suggest that not only the patients with unexplained productive coughs for more than 2-3 weeks, but also patients with other symptoms or even without symptoms or typical radiological findings, but with apical fibrocalcification would be be evaluated for active TB by sputum analysis and bronchoalveolar lavage if the result of sputum was negative, especially in endemic areas such as our country.…”

“…Although there were 108 cases with calcification or fibrosis out of the total 159 with abnormal findings in CXR, they didn't find any criteria for active TB in radiology. As they mentioned they didn't try for acid fast bacilli in calcified or fibrotic lesions, though they tried it in noncalcified nodules (25).…”

Background: Since tuberculosis (TB) is a major public health problem that is a leading cause of mortality and morbidity among infectious diseases worldwide, early diagnosis and treatment are important to control an effective tuberculosis (TB) and also the increasing number of patients with atypical manifestations of active TB. It suggests more evaluation for active TB in fibrotic lesion in CT scan. Objectives: We evaluated patients with each respiratory complaints and apical fibrocalcification in chest CT scan to detect active TB. Patients and Methods: This study was an observational cross sectional study and was carried out from July 2010 to September 2011 in our teaching hospital. Patients with apical fibrocalcification or fibrocystic lesion in lung CT scan (regardless of the size), without history of TB or other diseases which can cause these lesions were enrolled, then sputum analysis was performed, and in case the result was negative, we did bronchoalveolar lavage for them. Results: We gathered 40 patients out of which 15 patients were women. The average age was calculated at 64 ± 8 years old. In total 6 patients had positive results. Conclusions: According to our observations fibrocalcified lesions should be evaluated for detecting M. tuberculosis particularly in the endemic regions.

Imaging of thoracic tuberculosis in children: current and future directions

Tuberculosis continues to be an important cause of morbidity and mortality worldwide. It is the leading cause of infection-related deaths worldwide. Children are amongst the high-risk groups for developing tuberculosis and often pose a challenge to the clinicians in making a definitive diagnosis. The newly released global tuberculosis report from World Health Organization reveals a 50% increase in fatality from tuberculosis in children. Significantly, diagnostic and treatment algorithms of tuberculosis for children differ from those of adults. Bacteriologic confirmation of the disease is often difficult in children; hence radiologists have an important role to play in early diagnosis of this disease. Despite advancing technology, the key diagnostic imaging modalities for primary care and emergency services, especially in rural and low-resource areas, are chest radiography and ultrasonography. In this article, we discuss various diagnostic imaging modalities used in diagnosis and treatment of tuberculosis and their indications. We highlight the use of US as point-of-care service along with mediastinal US and rapid MRI protocols, especially in mediastinal lymphadenopathy and thoracic complications. MRI is the ideal modality in high-resource areas when adequate infrastructure is available. Because the prevalence of tuberculosis is highest in lower-resource countries, we also discuss global initiatives in low-resource settings.
