36.4). Chronic heart failure (CHF) is a clinical syndrome resulting in reduced cardiac output as a result of impaired cardiac contraction. Pleural and pericardial effusions are the most common radiologic manifestations of systemic lupus erythematosus (Fig 4.6, A and B).632 This diagnosis is rarely suggested by the radiologist. These cardiovascular changes include cardiomegaly, prominence of upper-lobe vessels, constriction of lower-lobe vessels, and prominent hilar vessels. The peripheral blood eosinophil count often rises over a few days during the initial course of disease—an evolution suggestive of the diagnosis. Increased permeability pulmonary edema is also known as ALI or ARDS in its severest form. We use cookies to help provide and enhance our service and tailor content and ads. These criteria identify a patient population with hypoxemia and bilateral infiltrates on chest radiograph whose condition cannot be explained by increased left atrial pressure (noncardiogenic). The chest radiograph shows bilateral infiltrates (see Figure 49-4), with mixed alveolar interstitial and opacities, especially Kerley lines. Kerley's C lines, which are rarely diagnosed by radiologists, result from thickening of the lung parenchymal interstitium and form a reticular pattern on chest radiographs. For hydrostatic reasons, perivascular edema is greatest in the gravitationally dependent regions, and the normal tethering action of the lung is therefore less in this region. Edema first spreads through the bronchovascular interstitium and later through the septal interstitium, but Kerley B lines are an infrequent observation in patients with congestive heart failure. Correlation with clinical and laboratory data is required to confirm the diagnosis. Lymphangitic spread of metastasis presents with Kerley lines, discrete nodules, and linear shadows, denoting a reticulonodular interstitial pattern of pulmonary disease. CXR shows acute alveolar edema with an air bronchogram in the right upper lobe (red arrow, a), and red circle, b)with Kerley A lines extending from the periphery to the hila and mediastinum (white arrows) The higher contrast resolution and fewer blind spots make CT the most sensitive imaging technique for detecting pulmonary metastasis. Normal echocardiographic structure and function argue strongly against pulmonary edema of cardiac origin. Other laboratory tests should be directed at potential causes of ALI. In cardiogenic pulmonary edema, the heart silhouette is often enlarged. ). The white blood cell count tends to be raised with a marked left shift. Laboratory results were remarkable for an elevated B-type natriuretic peptide (BNP) level of 1017 pg/mL and troponin-I of 0.107 ng/mL. Blood eosinophilia, often lacking at presentation, contrasts with frank alveolar eosinophilia in BAL fluid. Images in Clinical Medicine from The New England Journal of Medicine — Kerley's A, B, and C Lines. Finally, pulmonary artery catheterization may provide valuable information in patients with pulmonary edema and shock. All these causes of interstitial edema, except mitral stenosis and pulmonary veno-occlusive disease, are acute or recurrent processes; the pattern tends to be transient and changes rapidly. Kerley A Lines CHF with ALVEOLAR EDEMA and KERLEY A LINES 62-year-old male in the ICU with a tracheostomy with acute respiratory distress. Many causes of NPE exist, including drowning, acute glomerulonephritis, fluid overload, aspiration, inhalation injury, neurogenic pulmonary edema, allergic reaction, and adult respiratory distress syndrome (ARDS). In about 80% of individuals with H… When renal failure is the cause of pleural effusions, the associated congestive heart failure is secondary to fluid overload. In marked contrast with ARDS, extrapulmonary organ failure or shock is exceptional; however, a few cases of fatal IAEP have been reported. However, the benefit of routine use of pulmonary artery catheters in ALI patients is not well established, and this issue is the subject of an ongoing multicenter, randomized, controlled trial. Prominence of the left atrium without left ventricular enlargement, in combination with fine reticular opacities and prominence of upper lobe vessels, strongly suggests mitral valve disease.659 A clinical history of rheumatic fever and a murmur indicating mitral stenosis should be sufficient to confirm the diagnosis. By definition, arterial blood gas analysis will demonstrate significant hypoxia and intrapulmonary shunt. Chronic Kerley B lines may be ca… However, a minority of patients with AHF receive treatment within 1 hour of admission , ... or Kerley A lines (middle area), Kerley B, or C lines (inferior area); Score 2, interstitial or localized/mild alveolar pulmonary edema; Score 3, intense alveolar pulmonary edema . These are the well known Kerley lines, often spoken about but rarely seen. Because sepsis and pneumonia are the most common causes of ALI, cultures of blood, sputum (or airway aspirate), urine, wounds, and, if appropriate, cerebrospinal fluid should be obtained.

No focal deficits were noted on neurologic examination. High levels of IgE may be present as well. Kennedy et al. Interstitial pulmonary edema may be associated with normal or slightly reduced oxygenation (decreased PaO2) with a reduced PaCO2 from tachypnea. Typical clinical symptoms of CHF include shortness of breath, fatigue and ankle swelling.1 The finding of BAL fluid eosinophilia usually is sufficient, with differential counts greater than 25%, to obviate the need for lung biopsy; bacterial cultures of BAL fluid are sterile. Kerley B lines information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues. Kendig's Disorders of the Respiratory Tract in Children (Ninth Edition), Vincent Cottin, Jean-François Cordier, in, Clinical Respiratory Medicine (Fourth Edition), ), with mixed alveolar interstitial and opacities, especially, For the diagnosis of acute respiratory distress syndrome, use PaO, Bilateral infiltrates on frontal chest radiograph, Pulmonary artery occlusion pressure ⩽18 mmHg when measured or no clinical evidence of left atrial hypertension. 62-5; Video 62-1, loss of peribronchial and perivascular definition or cuffing) (Fig. Chest CT mainly shows ground glass opacities and air space consolidation, together with poorly defined nodules, interlobular septal thickening, and bilateral pleural effusions (in two thirds of patients)—an imaging pattern very distinct from that of ICEP that may evoke the diagnosis of IAEP. Other signs include jugular venous distension, an S3 gallop on heart examination, pitting edema, a palpable liver edge, and ascites. The B lines are characteristic of subacute and chronic left ventricular failure (Chapter 58), mitral valve disease (Chapter 75), lymphangitic carcinomatosis, viral pneumonia, and pulmonary fibrosis (Chapter 92). The past medical history should focus on prior history of coronary artery disease, valvular heart disease, hypertension, or cardiomyopathy. Therefore, a febrile response should suggest an interstitial pneumonia rather than interstitial edema. Once the magnitude of pulmonary edema is sufficiently severe to lead to persistent airway closure or alveolar flooding, it is very difficult to separate edema, atelectasis, and inflammation on chest radiographs. (Answer to question 3 is a). In ARDS, there is more likely to be a patchy peripheral distribution of edema and a paucity of such findings as septal lines and peribronchial cuffing. M.A. Chest radiography is valuable in diagnosing pulmonary edema. Bilateral B lines are commonly present in lungs with interstitial edema. This sign is, of course, of limited value in infants, because they are most likely to be in the supine position, have smaller gravitational induced differences because of their size, and normally have only slightly increased PA pressures relative to children and adults. IAEP manifests with the acute onset of cough, dyspnea, fever, and chest pain, sometimes with abdominal complaints or myalgias. 005Lu Cryptogenic Organizing Pneumonia – COP, 006Lu TB Cavitating Miliary Vietnamese Immigrant, 012Lu Sarcoidosis vs Silicosis in Cement Worker, 013Lu Rapidly Growing Head and Neck Lung Metatases, 015Lu Langerhans vs Inhalational Drug Cystic Disease 27M, 021LU Emphysema, Cor Pulmonale and Pulmonary Hypertension, 022Lu Active Sarcoidosis with Alveolar Consolidation, 023Lu Sarcoidosis with Wide Variety of Nodules, 026Lu Sarcoidosis Diffuse Ground Glass Stable 9 years, 034Lu Basal Bronchitis Bronchiectasis Young Female, 036Lu Sarcoidosis Stage III Calcified Nodes, 038Lu Amyloidosis Hilar Lymph Nodes Pericardium CAD, 040Lu Emphysema with Acute on Chronic Bronchitis, 041Lu Laryngotracheobronchial Papillomatosis, 044Lu Chronic Inactive TB  Lymphatic Distribution, 049Lu TB scrofula lymphadenitis pericarditis, Axial Interstitium, Peribronchovascular Interstitium, Bronchovascular Infiltrates, Bronchovascular Pneumonia, Chest X Ray, lung parts and fissures, CXR, Emphysema and Shapes of the Lung and Heart and Mediastinum, Hypersensitivity Pneumonitis, Chronic Hypersensitivity Pneumonitis, CHP, Idiopathic pleuroparenchymal fibroelastosis, PPFE, Interstitial Lung Disease – Introduction ILD, Interstitial Lung Disease ILD and Scleroderma, Interstitial Lung Disease, ILD and Connective Tissue Disease, Interstitial Lung Disease, ILD and Pulmonary Hypertension, PHA, Interstitial Lung Disease, ILD, and Rheumatoid Arthritis , RA, Interstitial Lung Disease, ILD, Usual Interstitial Lung Disease, UIP, Interstitial Lung Disease, IPF, and Hiatus hernia, Position Diseases Secondary Lobule Random Distribution, Position of Disease and the Secondary Lobule, Signs and Findings in Interstitial Disease, Signs and Findings of Mosaic Attenuation Pattern, Wegener’s granulomatosis with polyangiitis, GPA. Because pneumonia is the most common cause of ALI, there also may be focal consolidation with air bronchograms. Treatment options for a patient with Kerley lines depend on the cause. Other possible diagnostic studies in ALI include pulmonary artery catheterization and echocardiography. Cavitation is present in 6% to 7%20 and is more common with squamous cell carcinoma than adenocarcinoma. In hydrostatic edema, the radiographic opacities often develop centrally first. A changing course can be ascertained by examining old examinations and obtaining serial examinations. The classic Kerley lines are made by the thickening of the interlobular septa that carry the lymphatics (Kerley B lines are short thin lines, 1.5 to 2cm in length, seen in [aic.cuhk.edu.hk] Peribronchial cuffing (box) and kerley lines are seen (arrow). Most patients with acute pulmonary edema of any cause will present with dyspnea in which case the history of present illness should focus on dyspnea severity, time of onset, pace of onset, and associated symptoms. The history in suspected ALI should focus on eliciting the presence of one of the common causative conditions (see Table 1). The pattern typically is bilateral. The latter, noncardiogenic pulmonary edema (NPE), is caused by changes in permeability of the pulmonary capillary membrane as a result of either a direct or an indirect pathologic insult (see the images below). The presence of pleural effusion and cardiac enlargement alone is less specific; therefore, these require more careful review of serial examinations and correlation with clinical data to narrow the differential diagnosis (Chart 4.2). There may even be evidence of alveolar edema, with acinar nodules, confluent, ill-defined opacities with a perihilar distribution, and air bronchograms. Light index is used to calculate the size of pneumothorax from a posteroanterior view chest X-ray To calculate light index, 2 measurements are required DL – Diameter of the collapsed lung DH – Diameter of the hemithorax on the collapsed side Light index is given by: % of pneumothorax = 100−(DL3/DH3×100) Illustration: Assume that DL […] Kerley B lines are linear opacities seen on the chest radiograph. The histopathologic features of IAEP include acute and organizing diffuse alveolar damage together with interstitial alveolar and bronchiolar infiltration by eosinophils, intraalveolar eosinophils, and interstitial edema. The chest radiograph may show only bilateral interstitial edema, but most likely it will demonstrate areas of alveolar filling. If a hantavirus infection is suspected, a CBC and blood chemistry should be repeated every 8 to 12 hours. These are horizontal lines less than 2cm long, commonly found in the lower zone periphery. Adapted from Bernard GB, Artigas A, Brigham K, et al. Cardiogenic pulmonary edema: incidental finding in HRCT, smooth septal thickening with basal predominance (Kerley B lines), ground-glass opacity with a gravitational and perihilar distribution, thickening of the peribronchovascular interstitium (peribronchial cuffing) Lymphangitic carcinomatosis. Chronic renal failure is another cause of pulmonary edema with associated pleural effusions that is usually confirmed by correlation with the clinical history. Paul Stark, in Goldman's Cecil Medicine (Twenty Fourth Edition), 2012. a nd c are normal and b and d represent thickened interlobular septa in a patient with congestive heart failure. Any combination of additional clinical information indicating the development of chest pain, hemoptysis, sudden shortness of breath, pleural friction rub, decreased arterial Po2, or thrombophlebitis should be considered evidence for pulmonary embolism and thus would indicate more definitive evaluation.396. In the absence of other radiologic or clinical features of the common causes of pleural effusion with cardiac enlargement, this diagnosis may be considered. The pericardial effusion may be confirmed with ultrasound as an alternative to CT. ... Once-Weekly Insulin for Type 2 Diabetes without Previous Insulin Treatment ... Kerley’s B lines Calcification is unusual unless the metastasis is from osteosarcoma or chondrosarcoma. Treatment: Management approach mortality is decreased with angiotensin-converting enzyme inhibitors (ACE-inhibitors) or angiotensin II receptor blockers (ARBs), β-blockers, and spironolactone or eplerenone ; Conservative avoid excessive salt in the diet. Pulmonary interstitial edema is the most common cause of fine reticular opacities. Acute heart failure is the rapid onset or worsening of heart failure symptoms, and it is a common cause of hospitalization in older patients. Nodular shadows were present bilaterally, the largest measuring 18 mm. When the effusion is atypical (e.g., predominantly left sided) or if it increases after the pulmonary edema has begun to clear, the possibility of embolism should be considered. A febrile illness with clinical findings of pericarditis or myocarditis are helpful in suggesting inflammatory diseases, in particular viral and tuberculous infections or even poststreptococcal infection (e.g., rheumatic fever). IAEP differs from ICEP not only in its acute onset (less than 1 month) and severity but also in the absence of relapse after recovery. B lines are the ultrasound equivalent of the Kerley B lines found on chest X-ray. 25-38). Blood levels of B-type natriuretic peptide (BNP) are useful in emergency department patients with dyspnea and suspected cardiogenic pulmonary edema, however, their diagnostic accuracy in inpatients is unproven. The combination of cardiac silhouette enlargement caused by pericardial effusion with associated pleural effusions may be seen in patients with metastatic or inflammatory disease. Part 1in this two-part series on cardiomyopathies discussed classification, clinical signs and key types. Table 2. Abdominal tenderness on examination should be evaluated with imaging studies and amylase and lipase levels. Arterial blood gases are useful in assessing the severity of respiratory compromise. CHF, INTERSTITIAL EDEMA KERLEY A and B Ashley Davidoff MD CHF, INTERSTITIAL EDEMA KERLEY A and B 50-year-old male with CAD and CHF The CXR shows LA enlargement with widening of the carina, and findings consistent with interstitial edema characterized by interstitial fuzziness, Kerley B lines and peribronchial cuffing For an examination to be considered positive, there must be a minimum three B lines per view (Figure 3). They are identifiedas thin horizontal lines usually seen in the costophrenic angles, not being longer than 2cms in length and touching the pleural surface. CT depicts more accurately the extent of the disease, along the middle mediastinal structures and the involvement of paratracheal, subcarinal and pulmonary hilar areas, with better demonstration of calcifications, not usually obvious on routine X-rays [ 7 , 18 , 19 ] . Blood eosinophilia usually is lacking at presentation, and the diagnosis of eosinophilic lung disease may not be considered on admission. They are suggestive for the diagnosis of congestive heart failure, but are also seen in various non-cardiac conditions such as pulmonary fibrosis, interstitial deposition of heavy metal particles or carcinomatosis of the lung. A reticular or latticelike pattern also may be present and is more common inferiorly in an upright individual. Patients with acute cardiogenic pulmonary edema may have sudden, severe dyspnea. The Kerley lines represent interlobular sheets of abnormally thickened or widened connective tissue that are tangential to the x-ray beam (Fig. Serial chest radiographs frequently confirm this possibility. Kerley B lines represent interlobular lymphatics which have been distended by fluid or tissue. Pulmonary edema can be detected in adult humans on a chest radiograph when extravascular lung water (EVLW) is increased by approximately 35%. Likewise, creatine phosphokinase-MB (CPK-MB) and troponin levels are useful in patients with suspected cardiogenic pulmonary edema to rule out myocardial infarction. A patient with congestive heart failure may have right-sided heart enlargement and pleural effusion and is also at increased risk for developing a pulmonary embolism. Before alveolar flooding, plain chest radiographs typically show distended vascular shadows (particularly in the upper lung fields), enlargement and loss of definition of hilar structures, development of septal lines (Kerley lines) (Fig. Medications may help manage issues like parasites and cancers. When fluid leaks into the peripheral interlobular septa it is seen as Kerley B or septal lines. Although studies in children are limited, a summary of findings that allows separation of cardiogenic or hemodynamic edema, renal or overhydration edema, and injury or ARDS edema has been provided in adults.33,34 There is an inverted base-to-apex redistribution of blood flow in patients with heart failure. The combination of enlargement of the heart, pleural effusion in the absence of pulmonary vascular congestion, and signs of pulmonary interstitial or alveolar edema may be consistent with congestive heart failure. Air bronchograms indicate airless distal lung units and not the underlying cause. They are typically seen as a ladder up the side of the lungs beginning at the costophrenic angle. Heart failure is a pathophysiological state in which cardiac output is insufficient to meet the needs of the body and lungs. Acinar shadows, often confluent and creating irregular, patchy increases in lung density that obscure vascular markings, indicate the presence of alveolar edema. On lung examination, patients with ALI may have bilateral rales or evidence of consolidation, but these findings are non-specific. In the most severe cases, patients may develop cyanosis, the development of which signifies severe respiratory failure and impending death if not corrected quickly. In addition, hypoxia and sepsis may cause a metabolic acidosis. Thus, the physical examination in suspected ALI patients should be directed toward determining whether the patient's edema can be explained by elevated left atrial pressure and whether the patient has one of the potential causes of ALI. The absence of any history or physical examination evidence for volume overload or congestive heart failure in a patient with pulmonary edema strongly suggests ALI. These septal lines of edema are more clearly visible in older children and adults with chronic edema than in infants, presumably because they are wider. Pleural effusion is a common manifestation accompanying lung metastasis or may signify pleural metastasis. Potential respiratory exposures within the days before onset of disease have been reported (e.g., cave exploration, heavy dust inhalation, inhalation of smoke), suggesting that exposure to inhaled contaminants or any nonspecific injurious agent may trigger the disease. The next step in the evaluation of this pattern is to check for other signs that might suggest congestive heart failure. In these images. Congestive heart failure is one of the most common causes of pleural effusion, and it usually presents with a specific combination of cardiac and vascular findings. The vast majority of cases of hydrostatic pulmonary edema are of cardiac origin. 100-1A). Thickened septal lines may occur from a variety of processes, including fibrosis, pigment deposition, and pulmonary hemosiderosis. A fall in the serum albumin and a rise in the hematocrit may indicate a fluid shift from the patient’s circulation into the lungs. Diagnostic criteria for acute lung injury (ALI) acute respiratory distress syndrome (ARDS). Although recovery may occur without corticosteroid treatment, corticosteroid treatment usually is given for 2 to 4 weeks, with a starting dose of oral prednisone … 62-6), and perihilar haze indicating the presence of interstitial pulmonary edema. Based on these criteria, the most useful data in the diagnosis of acute lung injury are the history, chest radiograph, and arterial blood gases. The respiratory examination is characterized by the presence of wet rales, possible extending up to the apices of the lung. The early signs of pulmonary edema (interstitial edema) are the septal lines (Kerley B lines), which are horizontal lines seen laterally in the lower zones. The diagnosis rests heavily on the history, physical examination, and chest radiography. Recurrent effusions caused by congestive heart failure tend to duplicate the appearance of the effusion seen in the previous episode of failure. Although recovery may occur without corticosteroid treatment, corticosteroid treatment usually is given for 2 to 4 weeks, with a starting dose of oral prednisone or intravenous methylprednisolone of 1 to 2 mg/kg per day. A history of dietary indiscretion is common in patients with an acute exacerbation of chronic congestive heart failure. Lung function tests are performed only in the less severe cases and will show a mild restrictive ventilatory defect, reduced carbon monoxide transfer capacity, and increased alveolar-arterial oxygen gradient, measured as Po2(a−a). As mentioned above, acute pulmonary edema is often associated with an acute coronary event, so an electrocardiogram should be performed in all patients with suspected acute cardiogenic pulmonary edema. Kerley-B lines are seen as peripheral short 1-2 cm horizontal lines near the costophrenic angles. Patients may also give a history of recently worsening chronic congestive heart failure symptoms such as worsening dependent edema, orthopnea, and paroxysmal nocturnal dyspnea. Tachypnea, tachycardia, and crackles are present on examination. In several cases, IAEP developed soon after the initiation of tobacco smoking or change in smoking habits. Not only can normal pulmonary artery occlusion pressures exclude cardiogenic pulmonary edema, but the clinician can follow trends in the pulmonary artery catheter data to help guide fluid and vasopressor management. When alveolar flooding occurs, confluent parenchymal opacities develop. Several other diagnostic tests may be useful in patients with dyspnea or respiratory distress and suspected cardiogenic pulmonary edema. Long-term treatment … Particular attention should be paid to electrocardiographic signs of ischemia or infarction such as ST segment elevation, severe ST segment depression, new Q waves, or a new left bundle branch block. In addition, any cause of severe hypoproteinemia, including cirrhosis and nephrosis, may lead to interstitial edema. American Journal of Respiratory and Critical Care Medicine 149: 818–824. Although most of the radiographic signs of pulmonary edema are nonspecific, improved radiographic techniques in conjunction with improved understanding of the pathophysiology of pulmonary edema have enhanced the usefulness of the chest roentgenogram in the diagnosis of pulmonary edema.
