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. 1.Those resulting from the disease Miliary deposits appear as 1-3 mm diameter nodules, which are uniform in size and uniformly distributed 1-2. Only in 5% of patients, usually those with impaired immunity, go on to have progressive primary tuberculosis. Our patient had extensive pleural calcification secondary to old pulmonary tuberculosis. and specially in the region of Oporto it still mantains amoderate incidence (1). many times disabling to patients. For a general discussion please refer to the parent article: tuberculosis. When a calcified node and a Ghon lesion are present, the combination is known as a Ranke complex. It represents haematogenous dissemination of an uncontrolled tuberculous infection. The more striking finding, especially in children, is that of ipsilateral hilar and contiguous mediastinal (paratracheal) lymphadenopathy, usually right-sided 3. 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). Our patient had extensive pleural calcification secondary to old pulmonary tuberculosis. Miliary tuberculosis is uncommon but carries a poor prognosis. 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. In Portugal, Kim HY, Song KS, Goo JM, Lee JS, Lee KS, Lim TH. 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. 2001 Jul;42(4):430.

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 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. 1.2 Airway lesions, Lippincott Williams & Wilkins. Int J Health Geogr. Lippincott Williams & Wilkins. 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. Case Presentation Patients with post-primary pulmonary tuberculosis are often asymptomatic or have only minor symptoms, such as a chronic dry cough. (2007) ISBN:078177232X. Objectives. To become familiar with the multiple radiographic manifestations of thoracic sequelae in pulmonary tuberculosis, 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 ). Patients with AIDS demonstrate altered patterns of infection depending on their CD4 count. 5. It is seen both in primary and post-primary tuberculosis. 4. In the vast majority of cases, they develop in the posterior segments of the upper lobes (85%)1,7. 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. Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones.

Pulmonary tuberculosis: CT findings-early active disease and sequential change with antituberculous therapy. 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. 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. Imaging of Chest Wall Disorders. 2006 Aug 1. The Sequelar Lesions foundwere divided into : Pulmonary tuberculosis: up-to-date imaging and management. Although implants are seen throughout the body, the lungs are usually the easiest location to image. Radiology. The development of an air-fluid level implies communication with the airway, and thus the possibility of contagion. 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. Check for errors and try again. To evaluate tomographic changes in pulmonary tuberculosis (TB), degree of agreement among three radiologists regarding tomographic diagnoses, and sequelae following treatment. Generally, imaging workup starts with plain chest radiography. 2007 Jul 11;6:30. This pattern is seen in over 90% of cases of childhood primary TB, but only 10-30% of adults 1. Pneumothorax, empyema, and pyopneumothorax are complications of pulmonary tuberculosis, whilst infrequent but leading to significant morbidity and mortality.

When CD4 count drops to below 350 cells/mm3 pulmonary manifestations appear similar to run-of-the-mill post-primary infections (see below). Unable to process the form. Lippincott Williams & Wilkins. Stability of radiographic findings for 6 months distinguishes inactive from active disease. The clinical manifestations and evaluation of pulmonary TB will be reviewed here. Radiological studies may show a fibrotic, contracted lung; hilar elevation, lower … Nodal enlargement is also common at this stage. Lee JJ, Chong PY, Lin CB et-al. Small satellite lesions are seen in most cases 1. Hilar nodal enlargement is seen in only approximately a third of cases 1. 1999;210 (2): 307-22. (6)Joshua Burrill et al. - To be aware of the thoracic sequelae and complications of pulmonary tuberculosis. Chest radiology, the essentials. 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. Additional targeted therapies may be necessary for the setting of empyema, mediastinal complications, or hemoptysis. contrary to the evolution of most infectious diseases, 1. PTB infection often leaves long term sequelae of infection, particularly granulomatous nodules, cavitation, and fibrosis; distinguishing dormant disease from reactivation is … 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. These sequelae may involve the parenquima, airway, mediastinum, pleura, chest wall, or any combination of these structures. Int J Tuberc Lung Dis. If the treatment is successful, no residual abnormality remains. Post-primary infections are far more likely to cavitate than primary infections and are seen in 20-45% of cases. either the ones resulting from the disease or the ones consequent to therapeutic attitudes. 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. with the disease being one of the major causes of illness and death. Pulmonary Tuberculosis: Up-to-Date Imaging and Management. 10. We review potential acute and chronic complications of TB disease and current management approaches. Diagnosis and management of tuberculosis(TB) remains challenging and complex because of the heterogeneity of disease presentations. In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy. 19, Al-Hajjaj MS(1), Joharjy IA. 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. When CD4 counts drop below 200 cells/mm3 then the pattern of infection is more likely to resemble primary infection or miliary tuberculosis 4. Am J Respir Crit Care Med . Post-primary pulmonary tuberculosis Dr Dalia Ibrahim and Dr Omar Bashir et al. European Journal of Radiology 55 (2005) 158–172 The relationship between tuberculosis and mankind has been known for many centuries, Stability of radiographic findings for 6 months distinguishes inactive from active disease. The tests also allow prediction of the patients at risk of surgical complications and death. 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. However, lesions may appear anywhere in the lungs. (2007) ISBN:0781763142. Lobar consolidation, tuberculoma formation, and miliary TB are also recognized patterns of post-primary TB but are less common. Imaging of pulmonary infections. (2005) ISBN:078173889X.

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. Those complications include chronic obstructive pulmonary disease, hemoptysis, pneumothorax, pleural disease, tuberculosis, autoimmune disease, anthracofibrosis, chronic interstitial pneumonia, and malignancy. Occasionally patients may present with massive hemoptysis due to an erosion of a bronchial artery 1,3. Kazerooni EA, Gross BH. Transplantation . 617-637.

They are usually single (80%) and can measure up to 4 cm in size. 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. Some patients may show a paradoxical reaction on imaging. In accordance with the virulence of the organism and the defenses of the host, tuberculosis can occur in the lungs and in extrapulmonary organs. 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. 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. Predictors of radiological sequelae of pulmonary tuberculosis. Cavitation is uncommon in primary TB, seen only in 10-30% of cases 2. The clinical symptoms were dominated by a chronic sputum (74%), dyspnea (68%) and hemoptysis (34%). 12A, 12B, 12C and 13A, 13B). 2008;67 (1): 100-4. General thoracic surgery. Pulmonary tuberculosis (TB) is a contagious, infectious disease that attacks your lungs. It is usually the result of a contiguous inflammation from adjacent nodal involvement 3. Despite effective treatment, TB disease can lead to significant short-and long-term health consequences. The clinical manifestations of pulmonary TB in children and HIV-infected patients are discussed separately, as are the … sequelar lesions will remain, although there is no full restitution of lung parenchyma. In symptomatic patients, constitutional symptoms are prominent with fever, malais… Chronic inactive pulmonary tuberculosis and treatment sequelae: chest radiographic features. Late sequelae of tuberculous pleuritis include chronic persistent pleural effusion, empyema necessitatis, bronchopleural fistula, pleural malignancy, fibrothorax and pleural thickening … These nodes typically have low-density centers with rim enhancement on CT 1-3. 1.1 Parenchymal lesions, Therefore, Complications of pulmonary tuberculosis. 11. Rarely this material can be coughed up (known as lithoptysis) 2. 9. Calcification of nodes is seen in 35% of cases 2. Only in 5% of patients, usually those with impaired immunity, go on to have progressive primary tuberculosis. 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 1993;186 (3): 653-60. High resolution chest CT in patients with pulmonary tuberculosis: characteristic findings before and after antituberculous therapy. The spectrum of radiologic manifestations of PTB can pose a variety of diagnostic and management challenges. 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 . Müller NL, Franquet T, Lee KS et-al. 1.4 Pleural lesions, In 20-30% of cases, superimposed cavitation may develop. (1) Nunes C. (2) Kim et al. (2007) ISBN:0781757657. 2001 May 27. Pulmonary complications of TB can include hemoptysis, pneumothorax, bronchiectasis, extensive pulmonary destruction, malignancy, and chronic pulmonary aspergillosis. A variety of sequelae and complications can occur in the pulmonary and extrapulmonary portions of the thorax in treated or untreated patients. Treatment is usually only in the setting of progressive primary tuberculosis, miliary tuberculosis, or post-primary infection, and in general primary infections are asymptomatic. 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. RadioGraphics June 2001; 21,839-857 People with the germ have a 10 percent lifetime risk of getting sick with TB. 2008;191 (3): 834-44. 2007 Jul 11;6:30. implies sterilization of lesional focus, A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones. Post-primary pulmonary tuberculosis, also known as reactivation tuberculosis or secondary tuberculosis occurs years later, frequently in the setting of a decreased immune status. et al.Tuberculosis incidence in Portugal: spatiotemporal clustering. Administration of protracted courses of multiple antibiotics tailored to the sensitivity of the infective strain is the cornerstone of treatment. Post-primary tuberculosis , also known as reactivation tuberculosis or secondary tuberculosis usually occurs during the two years following the initial infection. 2. 1997;21 (4): 601-7. an important entity in the respiratory disease scenario. To present a radiographic review , 7. 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. Isolated tracheal infection by tuberculosis is rare but reported and typically results in irregular circumferential mural thickening. Eur J Radiol. (5)Mi-Young Jeung et al. First year Radiology Resident at Radiology Department - Centro Hospitalar de Vila Nova de Gaia - Portugal. Radiographic evidence of parenchymal infection is seen in 70% of children and 90% of adults 1. Extensive pulmonary parenchymal destruction may occur in primary or re-activation TB. Pulmonary manifestations of tuberculosis are varied and depend in part whether the infection is primary or post-primary.
