sequelae of pulmonary tuberculosis radiology

Cardiopulmonary imaging. Additional targeted therapies may be necessary for the setting of empyema, mediastinal complications, or hemoptysis. The primary infection is usually asymptomatic (the majority of cases), although a small number go on to have symptomatic hematological dissemination which may result in miliary tuberculosis. (2007) ISBN:0781763142. Lippincott Williams & Wilkins. A variety of thoracic sequelae and complications from pulmonary TB may occur and may involve the lungs, airways, vessels, mediastinum, pleura, or chest wall [47, 68–71] (Appendix 1, Figs. Only in 5% of patients, usually those with impaired immunity, go on to have progressive primary tuberculosis. Treatment is usually only in the setting of progressive primary tuberculosis, miliary tuberculosis, or post-primary infection, and in general primary infections are asymptomatic. Comment in Acta Radiol. Complications. 1.3 Mediastinal lesions, In symptomatic patients, constitutional symptoms are prominent with fever, malaise, and weight loss. Predictors of radiological sequelae of pulmonary tuberculosis. Kazerooni EA, Gross BH. with the disease being one of the major causes of illness and death. The imaging differential is dependent on the type and pattern of infection; consider: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 4. 2006 Aug 1. The clinical symptoms were dominated by a chronic sputum (74%), dyspnea (68%) and hemoptysis (34%). The more striking finding, especially in children, is that of ipsilateral hilar and contiguous mediastinal (paratracheal) lymphadenopathy, usually right-sided 3. Lee JJ, Chong PY, Lin CB et-al. General thoracic surgery. Patients with pulmonary tuberculosis (TB), even after cure, may develop further respiratory infections and lung disease, which may become chronic, leading to greater morbidity and mortality ( Hnizdo et al., 2000 ). 1 Nodal enlargement is also common at this stage. - Tuberculosis of the chest European Journal of Radiology 55 (2005) 158–172 (4)Yeon Joo Jeong et al. Miliary deposits appear as 1-3 mm diameter nodules, which are uniform in size and uniformly distributed 1-2. tuberculosis can still originate important sequelae, Post-primary tuberculosis , also known as reactivation tuberculosis or secondary tuberculosis usually occurs during the two years following the initial infection. The Sequelar Lesions foundwere divided into : Al-Hajjaj MS(1), Joharjy IA. Late sequelae of tuberculous pleuritis include chronic persistent pleural effusion, empyema necessitatis, bronchopleural fistula, pleural malignancy, fibrothorax and pleural thickening … Int J Health Geogr. It is seen both in primary and post-primary tuberculosis. Lippincott Williams & Wilkins. 2008;67 (1): 100-4. (4)Yeon Joo Jeong et al. Objectives. Generally, imaging workup starts with plain chest radiography. (2) Kim et al. Müller NL, Franquet T, Lee KS et-al. Leung AN. Shields TW, LoCicero J, Ponn RB. Thoracic sequelae and complications of tuberculosis. First year Radiology Resident at Radiology Department - Centro Hospitalar de Vila Nova de Gaia - Portugal. Imaging studies play a particularly important role both in guiding the diagnosis of pulmonary tuberculosis or its complications and in following the sometimes-unpredictable evolution of these lesions. Conventional radiography, Thorax, Respiratory system, Lung. 1993;186 (3): 653-60. In Portugal, High resolution chest CT in tuberculosis: evolutive patterns and signs of activity. To become familiar with the multiple radiographic manifestations of thoracic sequelae in pulmonary tuberculosis, 2014; 18(2):128-33 (ISSN: 1815-7920) Hicks A; Muthukumarasamy S; Maxwell D; Howlett D. The chest radiograph (CXR) is a key initial tool in the diagnosis of many lung conditions, including pulmonary tuberculosis (TB). Chronic inactive pulmonary tuberculosis and treatment sequelae: chest radiographic features. J Comput Assist Tomogr. For a general discussion please refer to the parent article: tuberculosis. although there is no full restitution of lung parenchyma. The authors reviewed chest x-rays from patients with sequelar lesions from pulmonary tuberculosis seen at the Pneumology Service of Centro Hospitalar de V.N.Gaia from 1994 to 2010 . Int J Health Geogr. Check for errors and try again. The development of an air-fluid level implies communication with the airway, and thus the possibility of contagion. Stability of radiographic findings for 6 months distinguishes inactive from active disease. Any patient with tuberculosis should be considered infective until sputum assessment is performed, and patients should be placed in respiratory isolation. The location of infection within the lung varies with both the stage of infection and age of the patient: Radiographic features depend on the type of infection and are discussed separately. Pulmonary tuberculosis: the essentials. Extensive pulmonary parenchymal destruction may occur in primary or re-activation TB. Occasionally these nodes may be large enough to compress adjacent airways resulting in distal atelectasis 1. Some patients may show a paradoxical reaction on imaging. TUBERCULOSIS IN INDIA • India is responsible for 1/3rd of the global cases of tuberculosis • 1.8 million new cases of tuberculosis are reported every year 47. (2007) ISBN:0781757657. Pleural effusions are more frequent in adults, seen in 30-40% of cases, whereas they are only present in 5-10% of pediatric cases 1. Complications of pulmonary tuberculosis. Chest radiology, the essentials. 1997;21 (4): 601-7. The tests also allow prediction of the patients at risk of surgical complications and death. Pulmonary tuberculosis: up-to-date imaging and management. Primary Pulmonary Tuberculosis. Patients with AIDS demonstrate altered patterns of infection depending on their CD4 count. Lippincott Williams & Wilkins. sequelar lesions will remain, Am J Respir Crit Care Med . Parenchyma § Upper lobes affected slightly more than lower § Alveolar infiltrate § Cavitation is rare § Lobar pneumonia is almost always associated with lymphadenopathy—therefore, lobar pneumonia associated with hilar or mediastinal adenopathy at any age should strongly suggest TB (2) Kim et al. To explore the strategy and curative effect of emergency transcatheter arterial embolization (ETAE) in patients with massive hemoptysis due to pulmonary tuberculosis and tuberculosis sequelae. Patients with post-primary pulmonary tuberculosis are often asymptomatic or have only minor symptoms, such as a chronic dry cough. RadioGraphics, May 1999. However, lesions may appear anywhere in the lungs. RadioGraphics June 2001; 21,839-857 (3)Luıs Curvo-Semedo et al. an important entity in the respiratory disease scenario. Having in mind that pulmonary tuberculosis primarily affects the lungs, lung damage is one of the most frequent complications, and it may lead to the lung failure. A productive cough which is often blood-stained may also be present 1. Imaging findings OR Procedure details The authors reviewed chest x-rays from patients with sequelar lesions from pulmonary tuberculosis seen at the Pneumology Service of Centro Hospitalar de V.N.Gaia from 1994 to 2010 . In primary pulmonary tuberculosis, the initial focus of infection can be located anywhere within the lung and has non-specific appearances ranging from too small to be detectable, to patchy areas of consolidation or even lobar consolidation. In a retrospective study of 15 patients who were treated with collapse therapy for pulmonary tuberculosis on an average 30 years previously, we found 16 instances of exudation in the residual pocket: four were sterile and without fistula, ten had bronchial fistulae, one had an esophageal fistula, and one was a tuberculous empyema without fistula. 6. recognition and understanding of the radiologic manifestations of thoracic sequelae and complications of tuberculosis is important to facilitate diagnosis. People with the germ have a 10 percent lifetime risk of getting sick with TB. Small satellite lesions are seen in most cases 1. Hilar nodal enlargement is seen in only approximately a third of cases 1. Poey C, Verhaegen F, Giron J et-al. many times disabling to patients. If the treatment is successful, no residual abnormality remains. 5. 1.1 Parenchymal lesions, 9. (2004) ISBN:0781736552. Tuberculosis, like syphilis, may involve practically any organ or tissue of the body. A total of 148 patients with massive hemoptysis due to pulmonary tuberculosis … Pneumothorax, empyema, and pyopneumothorax are complications of pulmonary tuberculosis, whilst infrequent but leading to significant morbidity and mortality. Radiology. A general discussion of tuberculosis is found in the parent article: tuberculosis; and a discussion of other mycobacterial infections of the lungs is found here: pulmonary Mycobacterium avium complex (MAC) infections. (6)Joshua Burrill et al. Diagnosis and management of tuberculosis(TB) remains challenging and complex because of the heterogeneity of disease presentations. 1.4 Pleural lesions, 8. This pattern is seen in over 90% of cases of childhood primary TB, but only 10-30% of adults 1. Frequent radiologic findings of pulmonary tuberculosis in infants are mediastinal or hilar lymphadenopathy with central necrosis and air-space consolidations, especially masslike consolidations with low-attenuation areas or cavities within the consolidation. 1.Those resulting from the disease Author information: (1)Department of Medicine , College of Medicine, King Saud University, Riyadh, Saudi Arabia. Kim HY, Song KS, Goo JM, Lee JS, Lee KS, Lim TH. 2008;191 (3): 834-44. When CD4 counts drop below 200 cells/mm3 then the pattern of infection is more likely to resemble primary infection or miliary tuberculosis 4. Pulmonary complications of TB can include hemoptysis, pneumothorax, bronchiectasis, extensive pulmonary destruction, malignancy, and chronic pulmonary aspergillosis. LYMPH NODES ENLARGEMENT 49. Pulmonary Tuberculosis: Up-to-Date Imaging and Management. Cross-sectional and descriptive study of 74 TB patients confirmed by sputum culture and chest computed tomography before (CT1) and 6 months after (CT2) drug therapy. 7. Int J Tuberc Lung Dis. Isolated tracheal infection by tuberculosis is rare but reported and typically results in irregular circumferential mural thickening. 10. Our patient had extensive pleural calcification secondary to old pulmonary tuberculosis. 1999;210 (2): 307-22. These nodes typically have low-density centers with rim enhancement on CT 1-3. Tuberculosis may be localized to the lungs, or involve other organs and regions of the body. Pulmonary manifestations of tuberculosis are varied and depend in part whether the infection is primary or post-primary. When a calcified node and a Ghon lesion are present, the combination is known as a Ranke complex. Calcification of nodes is seen in 35% of cases 2. 2001 Jul;42(4):430. et al.Tuberculosis incidence in Portugal: spatiotemporal clustering. To present a radiographic review , Exacerbations of chronic obstructive pulmonary disease (COPD), bronchiectasis, and pneumonia are more frequent after pulmonary TB ( Amaral et al., 2015, Byrne et … The primary infection is usually asymptomatic (the majority of cases), although a small number go on to have symptomatic hematological dissemination which may result in miliary tuberculosis. In 20-30% of cases, superimposed cavitation may develop. 1. Late sequelae of tuberculous pleuritis include chronic persistent pleural effusion, empyema necessitatis, bronchopleural fistula, pleural malignancy, fibrothorax and pleural thickening which may be associated with extensive calcification. Therefore, The relationship between tuberculosis and mankind has been known for many centuries, Miliary tuberculosis is uncommon but carries a poor prognosis. Those complications include chronic obstructive pulmonary disease, hemoptysis, pneumothorax, pleural disease, tuberculosis, autoimmune disease, anthracofibrosis, chronic interstitial pneumonia, and malignancy. Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones. Pulmonary rehabilitation plays a key role in the treatment of PTB sequelae. Burman WJ, Goldberg S, Johnson JL, et al. Since one of the commonest sites of primary infection is the lung, tuberculosis, in any other part of the human body, may be considered a complication of pulmonary tuberculosis. PULMONARY TUBERCULOSIS • 95% - MYCOBACTERIUM TUBERCULOSIS • 5% - ATYPICAL MYCOBATERIUM 48. Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones. It is also important to be aware of historical treatments for pulmonary tuberculosis that may still be seen incidentally radiographically nowadays, such as plombage, thoracoplasty, or oleothorax. Post-primary infections are far more likely to cavitate than primary infections and are seen in 20-45% of cases. Transplantation . Post-primary pulmonary tuberculosis Dr Dalia Ibrahim and Dr Omar Bashir et al. Collins J, Stern EJ. 2007 Jul 11;6:30. (2007) ISBN:078177232X. A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. 2001 May 27. 19, Radiographic evidence of parenchymal infection is seen in 70% of children and 90% of adults 1. The clinical manifestations and evaluation of pulmonary TB will be reviewed here. (5)Mi-Young Jeung et al. Endobronchial spread along nearby airways is a relatively common finding, resulting in relatively well-defined 2-4 mm nodules or branching lesions (tree-in-bud sign) on CT 1,3. In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy. [Medline] . The spectrum of radiologic manifestations of PTB can pose a variety of diagnostic and management challenges. It represents haematogenous dissemination of an uncontrolled tuberculous infection. Despite effective treatment, TB disease can lead to significant short-and long-term health consequences. tuberculosis pre-existent lung lesions, after a period of 14 yearsfrom the initial diagnostic of tuberculosis. Figure 1: gross pathology - cavitating pulmonary tuberculosis, Figure 2: gross pathology - miliary tuberculosis, Case 4: primary progressive pulmonary tuberculosis, Case 18: post-primary pulmonary tuberculosis, Case 30: post primary pulmonary tuberculosis, Case 33: endotracheal spread with tree in bud appearance, Upper zone changes in ankylosing spondylitis, pulmonary Mycobacterium avium complex (MAC) infections, differential of miliary pulmonary opacities, differential of alveolar pulmonary consolidation, doi:10.1148/radiographics.21.4.g01jl06839.
