Diagnosis and management of tuberculosis(TB) remains challenging and complex because of the heterogeneity of disease presentations. (1) Nunes C. Late sequelae of tuberculous pleuritis include chronic persistent pleural effusion, empyema necessitatis, bronchopleural fistula, pleural malignancy, fibrothorax and pleural thickening … Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones. Pulmonary destruction is usually the result of chronic, progressive, untreated pulmonary TB. In many countries, it is a reportable disease, and contact tracing will be performed. (2) Kim et al. When CD4 count drops to below 350 cells/mm3 pulmonary manifestations appear similar to run-of-the-mill post-primary infections (see below). et al.Tuberculosis incidence in Portugal: spatiotemporal clustering. 1 [Medline] . Some patients may show a paradoxical reaction on imaging. 1993;186 (3): 653-60. The Sequelar Lesions foundwere divided into : 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. Im JG, Itoh H, Shim YS et-al. 2. Stability of radiographic findings for 6 months distinguishes inactive from active disease. The spectrum of radiologic manifestations of PTB can pose a variety of diagnostic and management challenges. (2005) ISBN:078173889X. Conventional radiography, Thorax, Respiratory system, Lung. Jeong YJ, Lee KS. RadioGraphics June 2001; 21,839-857 Pneumothorax, empyema, and pyopneumothorax are complications of pulmonary tuberculosis, whilst infrequent but leading to significant morbidity and mortality. Unable to process the form. although there is no full restitution of lung parenchyma. 2001 May 27. Comment in Acta Radiol. 7. 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. Tuberculosis, like syphilis, may involve practically any organ or tissue of the body. Occasionally these nodes may be large enough to compress adjacent airways resulting in distal atelectasis 1. Pulmonary tuberculosis (TB) is a contagious, infectious disease that attacks your lungs. 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. Occasionally patients may present with massive hemoptysis due to an erosion of a bronchial artery 1,3. Therefore, These nodes typically have low-density centers with rim enhancement on CT 1-3. In Portugal, If the treatment is successful, no residual abnormality remains. 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. Extensive pulmonary parenchymal destruction may occur in primary or re-activation TB. 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. recognition and understanding of the radiologic manifestations of thoracic sequelae and complications of tuberculosis is important to facilitate diagnosis. Tuberculomas account for only 5% of cases of post-primary TB and appear as a well defined rounded mass typically located in the upper lobes. As the host mounts an appropriate immune response both the pulmonary and nodal disease resolve. Tuberculosis: A Radiologic Review In accordance with the virulence of the organism and the defenses of the host, tuberculosis can occur in the lungs and in extrapulmonary organs. in the next decades, 2001 Jul;42(4):430. PTB infection often leaves long term sequelae of infection, particularly granulomatous nodules, cavitation, and fibrosis; distinguishing dormant disease from reactivation is … AJR Am J Roentgenol. Pulmonary function tests allow the clinician to evaluate the residual lung function, and determine the mechanism of lung damage involved and the severity of pulmonary impairment. Chronic inactive pulmonary tuberculosis and treatment sequelae: chest radiographic features. 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. In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy.

Rarely this material can be coughed up (known as lithoptysis) 2. 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. In most cases, the infection becomes localized and a caseating granuloma forms (tuberculoma) which usually eventually calcifies and is then known as a Ghon lesion 1-2. 19, (2001) Radiographics : a review publication of the Radiological Society of North America, Inc. 21 (4): 839-58; discussion 859-60.

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. 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). A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. and specially in the region of Oporto it still mantains amoderate incidence (1). A productive cough which is often blood-stained may also be present 1. 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.

Pulmonary tuberculosis (TB) is a serious bacterial infection of the lungs. Tuberculosis may be localized to the lungs, or involve other organs and regions of the body. 1.3 Mediastinal lesions, 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 Only in 5% of patients, usually those with impaired immunity, go on to have progressive primary tuberculosis. Transplantation . It represents haematogenous dissemination of an uncontrolled tuberculous infection. 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. Pulmonary Tuberculosis: Up-to-Date Imaging and Management. Methods. Stability of radiographic findings for 6 months distinguishes inactive from active disease. Thoracic Sequelae and Complications of Tuberculosis. Exacerbations of chronic obstructive pulmonary disease (COPD), bronchiectasis, and pneumonia are more frequent after pulmonary TB ( Amaral et al., 2015, Byrne et … tuberculosis pre-existent lung lesions, after a period of 14 yearsfrom the initial diagnostic of tuberculosis. Administration of protracted courses of multiple antibiotics tailored to the sensitivity of the infective strain is the cornerstone of treatment. 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. Miliary deposits appear as 1-3 mm diameter nodules, which are uniform in size and uniformly distributed 1-2. Pulmonary tuberculosis: the essentials.

Nodal enlargement is also common at this stage. People with the germ have a 10 percent lifetime risk of getting sick with TB. It is seen both in primary and post-primary tuberculosis. Patients with post-primary pulmonary tuberculosis are often asymptomatic or have only minor symptoms, such as a chronic dry cough. In 20-30% of cases, superimposed cavitation may develop. 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. A broncholith is a relatively uncommon presentation which is due to erosion of a calcified lymph node into a bronchus, resulting in calcified material entering the lumen. Poey C, Verhaegen F, Giron J et-al. Eur J Radiol. Lippincott Williams & Wilkins. The development of an air-fluid level implies communication with the airway, and thus the possibility of contagion.

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 . Post-primary pulmonary tuberculosis, also known as reactivation tuberculosis or secondary tuberculosis occurs years later, frequently in the setting of a decreased immune status. 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. Isolated tracheal infection by tuberculosis is rare but reported and typically results in irregular circumferential mural thickening. 71(10):1488-91. Pulmonary tuberculosis: up-to-date imaging and management. To present a radiographic review , implies sterilization of lesional focus, an important entity in the respiratory disease scenario. Depending on the pulmonary, or extrapulmonary nature of the lesions, potential complications that may arise include: Parenchymal Lesions (4)Yeon Joo Jeong et al. Although implants are seen throughout the body, the lungs are usually the easiest location to image. 12A, 12B, 12C and 13A, 13B). (2007) ISBN:0781757657. 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 ). 2007 Jul 11;6:30. They are usually single (80%) and can measure up to 4 cm in size. Treatment is usually only in the setting of progressive primary tuberculosis, miliary tuberculosis, or post-primary infection, and in general primary infections are asymptomatic. These sequelae may involve the parenquima, airway, mediastinum, pleura, chest wall, or any combination of these structures. Thoracic sequelae and complications of tuberculosis. Lippincott Williams & Wilkins. Miliary tuberculosis is uncommon but carries a poor prognosis. General thoracic surgery. Post-primary tuberculosis , also known as reactivation tuberculosis or secondary tuberculosis usually occurs during the two years following the initial infection. Additional targeted therapies may be necessary for the setting of empyema, mediastinal complications, or hemoptysis. Collins J, Stern EJ. 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. - To be aware of the thoracic sequelae and complications of pulmonary tuberculosis. RadioGraphics, contrary to the evolution of most infectious diseases, The tests also allow prediction of the patients at risk of surgical complications and death. (2) Kim et al. 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. LYMPH NODES ENLARGEMENT 49. This pattern is seen in over 90% of cases of childhood primary TB, but only 10-30% of adults 1. 8. Our patient had extensive pleural calcification secondary to old pulmonary tuberculosis. 1. 2008;191 (3): 834-44. The clinical manifestations and evaluation of pulmonary TB will be reviewed here.

Cavitation is uncommon in primary TB, seen only in 10-30% of cases 2. The clinical manifestations of pulmonary TB in children and HIV-infected patients are discussed separately, as are the … Radiology. The mean time to the onset of respiratory symptoms related to pulmonary sequelae was 15.6 ± 8 years. Post-primary infections are far more likely to cavitate than primary infections and are seen in 20-45% of cases. Thoracic Sequelae and Complications of Tuberculosis. Complications of pulmonary tuberculosis. Patients with AIDS demonstrate altered patterns of infection depending on their CD4 count. the colonization of cavities by fungus, e.g. 9. However, lesions may appear anywhere in the lungs. In the vast majority of cases, they develop in the posterior segments of the upper lobes (85%)1,7. Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones. 11. It is usually the result of a contiguous inflammation from adjacent nodal involvement 3. 4. Our patient had extensive pleural calcification secondary to old pulmonary tuberculosis. Hilar nodal enlargement is seen in only approximately a third of cases 1. (6)Joshua Burrill et al. 5. Symptoms include a persistent bad cough, chest pain, and breathlessness. 2. Shields TW, LoCicero J, Ponn RB. sequelar lesions will remain, Int J Health Geogr. The clinical symptoms were dominated by a chronic sputum (74%), dyspnea (68%) and hemoptysis (34%). 6. The more striking finding, especially in children, is that of ipsilateral hilar and contiguous mediastinal (paratracheal) lymphadenopathy, usually right-sided 3. 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. Imaging of pulmonary infections. When CD4 counts drop below 200 cells/mm3 then the pattern of infection is more likely to resemble primary infection or miliary tuberculosis 4. In the majority of cases, post-primary TB within the lungs develops in either 1-2: Typical appearance of post-primary tuberculosis is that of patchy consolidation or poorly defined linear and nodular opacities 1. The lungs are the most common site of primary infection by tuberculosis and are a major source of spread of the disease and of individual morbidity and mortality. Small satellite lesions are seen in most cases 1. Any patient with tuberculosis should be considered infective until sputum assessment is performed, and patients should be placed in respiratory isolation. 2007 Jul 11;6:30. First year Radiology Resident at Radiology Department - Centro Hospitalar de Vila Nova de Gaia - Portugal. 2008;67 (1): 100-4. Radiographic evidence of parenchymal infection is seen in 70% of children and 90% of adults 1. (5)Mi-Young Jeung et al. Despite effective treatment, TB disease can lead to significant short-and long-term health consequences. Int J Health Geogr. Only in 5% of patients, usually those with impaired immunity, go on to have progressive primary tuberculosis. Pulmonary TB may lead to permanent damage of the lungs and affected structures.
