Differential diagnosis of tuberculous and malignant

Differential diagnosis The primary differential in this case was felt to be malignancy, including metastatic disease from a new primary, possible recurrence of her breast malignancy or primary pleural malignancy including mesothelioma Tuberculous pleural effusion (TPE) is still difficult to diagnose, especially in regions with a low incidence of tuberculosis. It is generally accepted that TPE is the most common form of extrapulmonary tuberculosis in younger populations (<35 years old). It can be manifested as primary or postprimary form of tuberculosis A uniformly blood-stained fluid (i.e., hematocrit greater than 1 percent) narrows the differential diagnosis of the pleural effusion to malignancy, trauma (including recent cardiac surgery),.. A definitive diagnosis of tuberculous pleuritis depends on the isolation of Mycobacterium tuberculosis in the sputum, PF or pleural biopsy specimens, or the demonstration of caseating granulomas in the parietal pleura

Differential Diagnosis of Tuberculous Exudative Pleurisy

About 44% of patients with tuberculous pleurisy showed circumferential pleural enhancement (35%) and nodular thickening (9%) on chest CT scan. Therefore, TB pleurisy should be included in differential diagnosis when these findings are seen at chest CT, especially in TB endemic area. Although these overlapping radiologic findings, th Differential diagnosis of tuberculous and malignant pleurisy using pleural fluid adenosine deaminase and interferon gamma in Taiwan Yung Ching Liu , Susan Shin-Jung Lee, Yao Shen Chen, Hui Zin Tu, Bao Chen Chen, Tsi Shu Huan The definitive diagnosis of TB pleural effusions depends on the demonstration of acid-fast bacilli in the sputum, pleural fluid, or pleural biopsy specimens. The diagnosis can be established in a majority of patients from the clinical features, pleural fluid examination, including cytology, biochemistry, and bacteriology, and pleural biopsy A pleural effusion is an abnormal collection of fluid in the pleural space resulting from excess fluid production or decreased absorption or both. It is the most common manifestation of pleural disease, with etiologies ranging from cardiopulmonary disorders to symptomatic inflammatory or malignant diseases requiring urgent evaluation and trea.. Tuberculous pleural effusion (TPE) results from Mycobacterium tuberculosisinfection of the pleura and is characterized by an intense chronic accumulation of fluid and inflammatory cells in pleural space (2). So far, no formal guidelines are available for diagnosis and treatment of tuberculous pleurisy

When the diagnosis of tuberculous pleurisy is made, the history (presence of pulmonary tuberculosis or other localization in the patient or immediate relatives), detection of mycobacterium tuberculosis in exudate, detection of extrapleural forms of tuberculosis, specific results of pleural biopsy and thoracoscopy data are of great importance Objectives To determine the age at which tuberculous pleural effusions occur, the radiological and biochemical characteristics of the effusions, the sensitivities of the various diagnostic tests, and the utility of combining clinical, radiological, and analytic data in diagnosis.. Methods We studied the case histories of 254 patients in whom tuberculous pleural effusions were diagnosed with. Pleuritis is defined as inflammation of the pleura. The pleural space, a thin fluid-filled space between the lung and the thoracic cavity, enables the smooth frictionless movement of the lung during respiration. It is lined by 2 layers of pleura: the visceral (covering the lung) and the parietal.

There is insufficient evidence that home remedies, such as turmeric, pleurisy root [5] or other herbs or teas help in pleurisy. References .

Rev Pneumol Clin 1989; 45:118 The differential diagnosis of pleural effusion can be daunting, but an organized approach that begins with the patient's history and focuses on identification of conditions that require urgent evaluation can guide appropriate care. Physicians investigating a pleural effusion should understand the limitations of the available diagnostic tools. Tuberculous pleurisy is the second most common extrapulmonary manifestation of TB , and its most common sequela is residual pleural thickening. Pleural thickening (>2 mm) has been reported to occur in ∼50% of cases . False-positive results due to tuberculous pleurisy are a common problem in ultrasound elastography and TUS examinations Pleural thickening is a descriptive term given to describe any form of thickening involving either the parietal or visceral pleura. It can occur with both benign and malignant pleural disease. According to etiology it may be classified as: benign pleural thickening. following recurrent inflammation. following recurrent pneumothoraces Tuberculous peritonitis is commonly classified as follows: wet type. most common (~90%) 1. . dry type. fibrotic-fixed type. Of note, there is considerable overlap between the three types. Tuberculosis in different organ systems may mimic alternate pathology so histopathological or laboratory evidence is often required to support suspicions on.

The diagnosis of tuberculous aetiology in pericardial effusions is important since the prognosis is excellent with specific treatment. The clinical features may not be distinctive and the diagnosis could be missed particularly with tamponade. With the spread of HIV infection the incidence has increased. The diagnosis largely depends on histopathology of the pericardial tissue or culture of. The differential diagnosis for a pleural exudate can be narrowed if LDH levels exceed 1000 IU/L, the proportion of lymphocytes is ≥80%, pleural fluid pH is <7.30 or there is pleural eosinophilia of >10%. tuberculous pleural effusion 67 or acute lupus pleuritis have a lower incidence of pleural fluid acidosis,. Pleural exudates are caused by more frequent specific pleurisy. And oncological and cardiac pathology, and differential diagnosis of tuberculosis provides for a wider use of pleural biopsy; the prevailing clinical form is tuberculosis of the intrathoracic lymph nodes, defined as secondary tuberculosis genetically related to the primary infection Diminished breath sounds over areas of consolidation (or pleural effusion) Depending on the degree of immunosuppression, TB in HIV-positive individuals may progress atypically or more rapidly. Always consider TB as a differential diagnosis in a young individual with hemoptysis. Complications [42

Background. Difficulties of differential diagnostics of exudative pleuritis due to pleura mesothelioma and such one of tubercular etiology can take a long time that is the reason of delayed well-timed and correct treatment order. Etiological diagnostics of exudative pleuritis has to be based on an integrated approach taking into account the data of clinical inspection of a patient, a. Currently, the ADA is widely used in the diagnosis of tuberculosis disease, and the ADA level in pleural effusion will not only help in the early diagnosis of tuberculous pleurisy, but also is an important indicator for differentiating tuberculosis pleural effusion and MPE.11 The tumor marker CEA is an important indicator of MPE as reported in. Summary. Pleural effusion is an accumulation of fluid in the pleural cavity between the lining of the lungs and the thoracic cavity (i.e., the visceral and parietal pleurae).The pleural fluid is called a transudate if it permeates (transudes) into the pleural cavity through the walls of intact pulmonary vessels. It is called an exudate if it escapes (exudes) into the pleural cavity through. Inflammation of the pleura characterized by a sharp chest pain that worsens during inspiration, coughing, or sneezing. Etiology includes viral infection, pulmonary embolism, tuberculosis, pericarditis, exudative pleural effusions, pneumothorax, and trauma including rib fractures.

Eosinophilic pleural effusion (EPE) is usually defined as a pleural effusion (PE) that contains ≥10% of eosinophils 1, 2.The relative incidence of EPE has been estimated at between 5% and 16% of all PEs 1, 3-5, but the clinical significance of pleural fluid eosinophilia remains unclear.Some early studies have shown that pleural fluid eosinophilia is associated with a decreased risk of a. Differential diagnosis of pleural effusions by fuzzy-logic-based analysis of cytokines. Download. .On the basis of the measured total protein and LDH concentrations in serum and pleural effusion, effusions of the BC, TB, CA and PN patients have been classified as exudative (ratio pleural effusion/ serum 40.5 for protein and 40.6 for LDH.

Tuberculous pleural effusion is straw-colored fluid contains fibrin and comprises approxi-mately 70% lymphocytes. The incidence of tuber-culous bacilli positive culture from pleural fluid cultures is up to 20%, and the data of PCR testing is various results. A pleural ADA of greater than 50 IU/L is suggestive of tuberculosis, but pleura Tuberculous pleuritis is a common manifestation of extrapulmonary tuberculosis (TB) and is the most common cause of pleural effusion in many countries 1-3.Pleural TB occurs as a result of a TB antigen entering the pleural space, usually through the rupture of a subpleural focus, followed by a local, delayed hypersensitivity reaction mediated by CD4+ cells 4 In this respect, although differential diagnosis must be a priority, it is often difficult due to the similar biochemical profiles and the predominance of lymphocytes in both conditions. The gold standard for diagnosis of pleural tuberculosis is the identification of Mycobacterium tuberculosis in pleural fluid or tissue 4 Study population. In total, 129 individuals were enrolled in this study including patients with pulmonary TB (PTB) (n = 39), tuberculous pleurisy (TBP) (n = 28), malignant pleural effusion (MPE) (n = 21), latent tuberculosis infection (LTBI) (n = 20), and healthy controls (HC) (n = 21).All the patients were recruited from Wuxi Fifth People's Hospital, Zhuji People's Hospital, and Fudan.

Clinical Features in the Diagnosis of Pleural Effusions and Identifying Etiology: 1,2. Pleural effusions can be easily identified on chest radiography, physical examination findings include dullness to percussion, decreased tactile fremitus and decreased (or absent) breath sounds. Hemoptysis: Malignancy, PE, TB Of 31 exudative effusions with a lymphocytic predominance, 30 were due either to tuberculosis or neoplasm. No tuberculous effusions had more than 1% mesothelial cells, while most other effusions contained at least 5% mesothelial cells. Pleural fluid cytological studies showed malignant cells in 33 of 43 patients with effusions due to tumor The differential diagnosis for tuberculous spondylitis includes metastatic disease, low-grade pyogenic infection (eg, brucellosis), fungal infection, and sarcoidosis, all of which have similar imaging characteristics. In the early stage of infection, imaging appearances are entirely nonspecific Pleurisy - Differential Diagnosis of the thoracic spine. Pleurisy. Pleurisy is inflammation of the parietal pleura that typically results in pleuritic pain and has a variety of possible causes (Boissonnault and Bass 1990). Clinically produces a sharp localized pain, made worse on deep inspiration or coughing, and occasionally twisting or.

Introduction: Although pleural effusion is a common clinical manifestation, the differential diagnosis of the cause of the pleural effusion is often challenging, especially in the early differentiation of tuberculous pleurisy (TP) from other pleural effusion. Case report: We present a previously healthy man who had no contagious or TB contact but developed massive tuberculous pleural effusion. In some parts of the United States, pleural tuberculosis accounts for < 5% of all cases of tuberculosis.1 In some countries, the incidence of pleural tuberculosis is much higher. It is generally linked to the local prevalence of tuberculosis. Pleurisy with effusion as a complication of primary pulmonary tuberculosis has been reported to occur in 2 to 38% of children with pulmonary disease, but. pericardial fluid cytology: positive.

Tuberculous pleural effusion in non-HIV-infected patients is almost invariably unilateral and seldom massive. In one retrospective study, only 19 of 113 (17%) tuberculous pleural effusions occupied more than two-thirds of the hemithorax on posteroanterior upright chest radiographs. Differential Diagnosis . Benign asbestos-related effusion. Pleural Effusions. Pleural effusions are produced by a wide variety of causes. Infectious processes including bacteria, viruses, tuberculosis, atypical mycobacterium, fungus, as well as parasites account for a substantial percentage of these effusions. This chapter will help to elucidate the broad differential diagnosis that must be entertained. To evaluate and compare the diagnostic efficiency of serum (s) and pleural (p) levels of adenosine deaminase (ADA)-1, ADA-2, total ADA, and interferon-gamma (IFN-γ) for the differential diagnosis of pleural tuberculosis (TB). Clinical and analytic data of 93 consecutive patients with pleural effusions from May 2012 to February 2013 were prospectively evaluated The most important aspect of forming a differential diagnosis of pleural effusion is performing a thoracentesis and obtaining a sample of the pleural fluid. Analysis of this fluid yields a large amount of information regarding the cause. A pleural effusion occurs when excess fluid builds around the lungs. Pleural effusions can be diagnosed on. Tuberculous pleural effusion is one of the most common forms of extrapulmonary tuberculosis (TB). The immediate cause of the effusion is a delayed hypersensitivity response to mycobacterial antigens in the pleural space. For this reason microbiological analyses are often negative and limited by the lengthy delay in obtaining results. In areas with high TB prevalence, pleural fluid adenosine.

TB or Not TB: Differential Diagnosis and Imaging Findings

A pleural fluid adenosine deaminase (ADA) has been used globally to assist in the diagnosis of a tuberculous pleural effusion (TPE) with a notable negative predictive value. We report a case of a patient with a negative pleural fluid ADA who was found to have culture-positive and biopsy-proven Mycobacterium tuberculosis. This case shows the importance of pursuing gold standard diagnostic. Porcel JM, Vives M, Cao G, et al. Biomarkers of infection for the differential diagnosis of pleural effusions.

Recommendations for Treatment of Pleurisy. processing.... May 8, 2007 -- A review published in the May 1 issue of American Family Physician describes diagnosis and treatment strategies for pleurisy. The authors recommend history, physical examination, and chest radiography for all patients with pleuritic chest pain ADA determination in body fluids (spinal, pleural, ascitic, pericardial) for the diagnosis of tuberculous meningitis , tuberculous pleurisy peritoneal TB and pericardial TB has a high positive predictive value, especially in high endemic countries. Pleural fluid elevated adenosine deaminase (ADA) concentrations > 45 to 60 U/L is 100 percent. Adenosine deaminase (ADA) can aid in the diagnosis of tuberculous pleural effusions, but false-positive findings from lymphocytic effusions have been reported. The purpose of this study is to assess the ADA levels in nontuberculous lymphocytic pleural effusions (lymphocyte count >50%) of different aetiologies. Altogether, 410 nontuberculous lymphocytic pleural fluid samples were consecutively.

However, the differential diagnosis of ITB and CD still represents a challenging clinical problem, especially in the developing countries with a high incidence of tuberculosis where the misdiagnosis and missed diagnosis may lead to serious adverse consequences [3,4,5] In the case illustrated in Figure 5, the key to the differential diagnosis is knowledge of the patient's CD4 cell count and the fact that this chest radiographic presentation of TB may occur at a low CD4 cell count. Pleural effusions can be seen with TB at both high and low CD4 cell counts, but intrathoracic adenopathy is seen much more. Tuberculous empyema is a chronic active infection of the pleural space. It may be a consequence of infection extending from other sites after pneumonectomy, or it can occur when the contents of a bronchopleural fistula cavity are released into the pleural space. 21 TBPE can also cause fibrous thickening of the visceral pleura, preventing lung expansion (trapped lung)
