Differential diagnosis of pleural effusion

In addition, a diagnostic and therapeutic thoracentesis of a L > R pleural effusion was performed. Pleural fluid studies were suggestive of a transudative process, though with some abnormal characteristics (including lymphocyte predominance, as well as presence of signet cells) Differential Diagnosis of Pleural Effusions Carcinoembryonic antigen (CEA), orosomucoid beta 2 microglobulin, and alpha fetoprotein were quantified in the pleural fluid and serum of 58 hospitalized consecutive patients in order to differentiate malignant from nonmalignant effusions. Cytologic examination of the effusions was also performed Differential Diagnosis of Pleural Effusions JMAJ 49(9•10): 315-319, 2006 Tetsuo Sato*1 Abstract A variety of disease states are associated with the development of pleural effusions, which sometimes makes the differential diagnosis problematic. Pleural effusions can be classified into two categories, transudative an

Several primary tumors can metastasize to the pleura, and pleural effusions are often associated with carcinoma of breast, lung, or stomach. On the other hand, pleural effusion is a common sign of decompensation in heart failure, and this latter syndrome can occur superimposed on various malignancies Transudative pleural effusion. Considerations in the differential diagnosis of transudative pleural effusion include the following: Congestive heart failure (most common) Cirrhosis with hepatic hydrothorax. Nephrotic syndrome. Peritoneal dialysis/continuous ambulatory peritoneal dialysis. Hypoproteinemia Many pleural fluid tests are useful in the differential diagnosis of exudative effusions. Other tests helpful for diagnosis include helical computed tomography and thoracoscopy. Pleural effusion.. Cell differential A high lymphocyte count is most commonly associated with a tuberculous pleural effusion (TPE), but chronic effusions can often have a high lymphocyte ratio of 50% or more. The most common aetiologies which produce lymphocytic effusions are tuberculosis (TB), malignancy and CCF 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

Differential Diagnosis of Pleural Effusio

Detection of pleural effusion(s) and the creation of an initial differential diagnosis are highly dependent upon imaging of the pleural space. Conventional chest radiography and computed tomography (CT) scanning are the primary imaging modalities that are used for evaluation of all types of pleural disease, but ultrasound and magnetic resonance. DIFFERENTIAL DIAGNOSIS OF PLEURAL EFFUSIONS 297. sions. An attempt was made to evaluate the clinical value of combined assays of several markers in pleuralfluids. METHODSAND MATERIALS Sampling Pleural effusions were obtained from 58 consecutive hos. A systematic approach to analysis of the fluid in conjunction with the clinical presentation allows clinicians to diagnose the cause of an effusion, narrow the differential diagnoses, and design a management plan in a majority of patients who undergo pleural fluid analysis. An approach to pleural fluid analysis will be presented here Purpose: To investigate the value of spectral CT in the differential diagnosis of benign from malignant pleural effusion. Method and materials: 14 patients with benign pleural effusion and 15 patients with malignant pleural effusion underwent non-contrast spectral CT imaging. These patients were later verified by the combination of disease history, clinical signs and other information with the.

Differential Diagnosis of Pleural Effusions: Clinical

Pleural effusions occur as a result of increased fluid formation and/or reduced fluid resorption. The precise pathophysiology of fluid accumulation varies according to underlying aetiologies. As the differential diagnosis for a unilateral pleural effu-sion is wide, a systematic approach to investigation is necessary. The aim is to establish. Pleural effusions are a common medical problem with more than 50 recognised causes including disease local to the pleura or underlying lung, systemic conditions, organ dysfunction and drugs.1 Pleural effusions occur as a result of increased fluid formation and/or reduced fluid resorption. The precise pathophysiology of fluid accumulation varies according to underlying aetiologies The differential diagnosis is presented in Table 1.9, 10 Often consolidation, lymphadenopathy, and/or unilateral pleural effusion; cavitation common. Acid-fast bacilli Gram stain, sputum. Pleural aspirate can narrow the differential diagnosis significantly. First, appearance is important ( Table 2 ).

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. Pleural effusion in which a high proportion of the cells are eosinophils is not a widely recognized phenomenon. One purpose of this paper is to report that the cause of such an effusion may be a fungus infection. Two patients with eosinophilic effusion are described in detail, and several others of which we have knowledge are mentioned briefly Pleural fluids from 182 patients were studied prospectively. Although red blood cell (RBC) counts of greater than 10,000/cu mm were common with all types of effusions, an RBC count greater than 100,000/cu mm strongly suggested malignant neoplasm, pulmonary infarction, or trauma.

Pleural effusions may be classified as being either a transudate or exudate according to the protein concentration. Transudate (< 30g/L protein) Heart failure (most common transudate cause) Hypoalbuminaemia (liver disease, nephrotic syndrome, malabsorption) Hypothyroidism. Meigs' syndrome 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.

Leila Antonangelo, Francisco Suso Vargas, Marcia Seiscento, Sidney Bombarda, Lisete Teixera, Roberta Karla Barbosa de Sales. DOI: 10.1590/S1807-59322007000500009 PURPOSE: To evaluate the clinical and laboratory characteristics of pleural effusions. Most (82%) of malignant effusions were exudative. The primary site could be assessed by cytological examination in 57.14% of malignant effusions. Conclusions: The most useful test in establishing the diagnosis of pleural effusion is pleural fluid cytology and pleural fluid cell count Considerations in the differential diagnosis of transudative pleural effusion include the following: Congestive heart failure (most common) Cirrhosis with hepatic hydrothorax Nephrotic syndrome Pe. Some imaging findings may help narrow the list of potential causes of the pleural effusion. Bilateral pleural effusions: Most commonly seen in volume overload states (e.g., CHF) Differential diagnosis should also include malignancy, lupus, and constrictive pericarditis. Massive effusions may occur in: Malignanc

DIFFERENTIAL DIAGNOSIS. Pleural effusions are quite common, diagnosed in over 1 million patients each year in the United States (5). Over 50 etiologies are known, and in the United States the most common causes are heart failure, pneumonia, malignancy, and pulmonary embolism (6). In children, pneumonia is the most common cause of pulmonary. The differential diagnosis of pleural fluids is wide and may indicate the presence of pleural, pulmonary or extrapulmonary disease. When we attempt to identify the cause of the pleural effusion, most patients undergo various diagnostic procedures Objective and background: Determining the aetiology of an effusion involves assessing if it is an exudate or a transudate. However, a reliable test for determining the aetiology of a pleural effusion is lacking. Pleural viscosity has a high sensitivity and specificity and a high positive and negative predictive value for discriminating exudative and transudative pleural effusions

The Differential Diagnosis of Bilateral Pleural Effusion

There is no gold standard diagnostic technique for differential diagnosis of pleural effusion. The available traditional methods like cytology and microbiology are time-consuming. Depending on the laboratory consultant's expertise, there is a chance of subjective bias affecting the patients' management. Radiological investigations (USG/CT. The negative predictive value of a negative ANA in pleural fluid is so high that it eliminates lupus from the differential diagnosis. In lupus patients with effusions from causes other than lupus, the pleural-fluid ANA was low-positive (1:40 to 1:80) or negative. The majority of non-lupus pleural effusions with positive ANAs were malignant Pleural effusion is an extremely common problem; however, the diagnosis of pleural effusion remains challenging due to its diverse aetiologies. Malignant pleural effusion (MPE) is one of the leading causes of unilateral pleural effusion, and many clinical guidelines have recommended diagnostic strategies for MPE [1, 2]
