J Am Vet Med Assoc 2008; 233: 1742-1747. … The most common entities with this pattern are miliary tuberculosis, pneumoconiosis, sarcoidosis, metastases, and … If your cat develops a tumor that is prone to metastasize to the lungs, your veterinarian will likely recommend chest x-rays. Pneumonitis--viral, parasitic, septicemia, metabolic (uremia), inhalant, toxic, Disease in transition--pneumonia, hemorrhage. Summation of multiple linear opacities can lead to a net-like or reticular pattern. Tachypnea (rapid breathing) 4. Transbronchial biopsy yielded lung tissue containing multiple nodules of smooth muscle, consistent with benign metastasizing leiomyoma. If the disease process does not spread to an adjacent lung lobe, the border of the affected lobe is sharply demarcated ("lobar sign"). Miliary pattern consists with the presence of multiple small (usually 1 to 3 mm in diameter) nodules in the lung with sharp margins. The radiologic features that help in the differential diagnosis are discussed. 3. Powered by Pure, Scopus & Elsevier Fingerprint Engine™ © 2020 Elsevier B.V. We use cookies to help provide and enhance our service and tailor content. Distribution of the changes allows determining the most likely cause for the alveolar infiltrate: Table 1. Selected differential diagnoses for diffuse and focal interstitial pulmonary patterns. Underexposure, expiration and patient-related artifacts such as obesity will result in an increased opacity of the thoracic cavity which may be misinterpreted as an interstitial pulmonary pattern. Vet Clin Small Anim 2009; 39: 719-732. The most common entities with this pattern are miliary tuberculosis, pneumoconiosis, sarcoidosis, metastases, and hypersensitivity pneumonia. A subcategory of structured or nodular pattern featuring < 3mm punctate nodules that coalesce. In the following the different pulmonary patterns, their radiographic appearance and significance, but also an alternative approach to interpretation of the pulmonary parenchyma in dogs and cats is described. He is an indoor cat and has not had a diet change. Miliary lung disease revisited. Kogan, et al. Interpretation of thoracic radiographs is often too focused on indentifying a specific pulmonary pattern rather than taking all findings into account. Each of these structures is radi-ographically invisible on its own. Pulmonary infiltrates with eosinophils (PIE). Radiographic signs of a bronchial pulmonary pattern are: Excessive number of opaque rings and lines, best recognized in the periphery of the lungs where normal bronchial walls should not be visualized anymore. AB - This article reviews the high-resolution computed tomography imaging features of miliary pattern, a characteristic radiologic manifestation of diffuse micronodular lung disease. The blood volume circulating in the pulmonary vasculature has an impact on the overall pulmonary opacity. Then, a decision has to be made if the pulmonary parenchyma is too opaque or too radiolucent. Has Symptoms Has Symptoms Has Symptoms Has Symptoms Has Symptoms Hello I have noticed a new rash in my cat. On a daily basis we have to deal with patients with pulmonary abnormalities that don't fit into one of the classical pulmonary patterns. However, x-rays cannot detect small tumors (less than 3 millimeters in size), so computed tomography (CT … miliary disease and larger nodules and masses are con-sidered separately. C{\'a}ceres and {Andreu Soriano}, Jorge". If the lungs are too radiopaque, and artifacts and extrapulmonary disease have been ruled out as a cause, the type of opacification using pulmonary patterns, and most importantly the distribution (focal, lobar, multifocal or diffuse) and the location (cranioventral, caudodorsal etc.) The radiologic features that help in the differential diagnosis are discussed.". The cats present with severe respiratory distress characterized by tachypnea, increased respiratory effort or open mouthed breathing. 1. The lung appears as if a white screen door is superimposed onto it. Aggregations of cells in the supportive lung tissues result in a nodular pattern. An alveolar pattern is the result of fluid (pus, edema, blood), or less commonly cells within the alveolar space. 8. 2007 Textbook of Veterinary Diagnostic Radiology 5th ed. And radiographs are most helpful in deciding which one to choose. Disseminated form of primary alveolar cell carcinomas. Miliary pattern is a well-known chest radiograph pattern, 1 consistent with the presence of multiple nodules in the lung (Fig 1). The miliary pattern consists of multiple small (< 3 mm) pulmonary nodules of similar size that are randomly distributed throughout both lungs . S. Mauleón, E. Pallisa, J. Majó, M. Martinez-Rodriguez, J. Cáceres, Jorge Andreu Soriano, Research output: Contribution to journal › Article › Research › peer-review. 1. In a miliary or reticulonodular lung pattern the radiograph looks as if a snowstorm is blustering. Causes of miliary lung pathology Miliary metastatic neoplasia. Fail to consider normal vs. abnormal Few diseases involve one compartment Can’t make diagnosis from radiograph For beginners (and maybe intermediates), too confusing Vet Radiol Ultrasound 2005; 46: 478-484. Pulmonary nodules have to reach a considerable size to be recognized on a radiograph (7-9mm).10 The areas where nodules can best be detected are the periphery of the lungs and the portion of the lung superimposed with the cardiac silhouette and the diaphragm where superimposition of other pulmonary structures is limited. The most important decision is whether the airways (alveoli or bronchi) are affected by the disease process. The radiologic features that help in the differential diagnosis are discussed. The respiratory system consists of the large and small airways and the lungs. Overcirculation of the pulmonary vasculature will increase the opacity of the lungs due to the increased blood content, whereas hypoperfusion of the lungs will lead to increased radiolucency of the lungs. The interstitial space consists of alveolar and interlobular septa as well as microscopic vessels. Mai, et al. The overall pulmonary opacity is not markedly increased as the alveoli are still air-filled, in fact, hyperinflation of the lungs can result from lower airway obstruction.7 Chronic bronchial disease can lead to bronchial dilation and loss of normal tapering of the bronchi (bronchiectasis). The diagnosis is similar to that for primary lung tumors. Air-bronchograms may not be visible early on in the disease process, their absence does not rule out alveolar disease. Vet Radiol Ultrasound 1974; 15: 3-24. An unstructured interstitial pattern is present in the dorsocaudal lung fields Structured interstitial (nodular) pattern. 2-4 The intent is that focusing on the compartment of the lung that is abnormal—that is, the pattern—leads to an organized approach to image evaluation. Download : Download high-res image (20KB) Download : Download full-size image Fig. The most common entities with this pattern are miliary tuberculosis, pneumoconiosis, sarcoidosis, metastases, and hypersensitivity pneumonia. Gradual weight loss 7. It is important to recognize the presence of bronchiectasis as those patients are more prone to chronic respiratory infections, due to impaired mucociliary clearing function. Lameness i… The lung volume is usually unchanged, but may be smaller with pulmonary fibrosis.9 Alveolar disease in transition (early or resolving) with partially fluid-filled or partially collapsed alveoli results in the same appearance as alveolar septal thickening, therefore the same principles are applied when it comes to pattern distribution. The unstructured interstitial lung pattern is the most challenging and most over-diagnosed lung pattern. The term miliary opacities refers to innumerable, small 1-4 mm pulmonary nodules scattered throughout the lungs.It is useful to divide these patients into those who are febrile and those who are not.. Additionally, some miliary opacities are very dense, narrowing the differential - see multiple small hyperdense pulmonary nodules. A 30-year-old woman presented with progressive dyspnea on exertion and a rapidly-growing uterine mass. The presence OF disseminated miliary lesions in the lungs, demonstrable on the chest roentgenogram, is of frequent occurrence and is seen in a wide variety of diseases. End-on projection of thickened bronchi results in rings or "donuts", whereas long axis projection of a thickened bronchus results in two parallel lines "tram lines". Raleigh, NC, USA, How to Make Sense of Pulmonary Patterns in Dogs and Cats, World Small Animal Veterinary Association World Congress Proceedings, 2010, Gabriela S. Seiler, Dr.med.vet., DECVDI, DACVR, Interpretation der Lungenmuster beim Hund und bei der Katze, Gabriela S. Seiler, Dr. med. Dive into the research topics of 'Miliary lung disease revisited'. Gabriela S. Seiler, Dr. med. Hemoptysis (coughing up blood) 8. Vascular pattern is not a "pulmonary pattern" strictly speaking, as it does not reflect pulmonary but rather cardiovascular pathology. Low energy level and lethargy 5. Table 3. If this is the case, airway sampling such as trans-tracheal aspiration or bronchoalveolar lavage may be very helpful. This results in a generalized increase in pulmonary opacity with a hazy appearance, the outline of the pulmonary vessels and airway walls becomes unsharp. More than 80 conditions capable of producing this appearance have been recorded (1–3). Miliary disease has a relatively low reported prevalence (11%–28% in small series) and is usually associated with acute and severe clinical manifestations (, 7,, 13). The disease usually manifests as bilateral and diffuse nodules less than 3 mm in size (, Fig 14,,). Small nodular lung opacities correspond to miliary pattern. However, the model of pulmonary patterns is not a perfect one, as many diseases involve several and varying components of the lungs, and disease in transition can move from one component to the other. Pulmonary nodules have to reach a considerable size to be recognized on a radiograph (7-9mm). Miliary lung lesions in a foal. Subsequent hysterectomy revealed an atypical cellular leiomyoma. Full collapse of RM lung lobe - looks like triangle of soft tissue where lung … He is on no medications and no other medical problems Has Symptoms Has Symptoms My cat has a single sca… Smaller, ill-defined patches of alveolar pattern can coalesce into a more homogeneous soft tissue opacity where the only remaining gas is retained in the larger bronchi, seen as "air-bronchograms". According to the distribution of the nodules in relation to the secondary lobule, high-resolution computed tomography findings divide miliary patterns into 3 groups: centrilobular, perilymphatic, and random presentation. Radiographic signs include border effacement with other soft tissue structures such as the pulmonary vessels, cardiac silhouette or diaphragm.

N2 - This article reviews the high-resolution computed tomography imaging features of miliary pattern, a characteristic radiologic manifestation of diffuse micronodular lung disease. Begnini, et al. Mauleón, S., Pallisa, E., Majó, J., Martinez-Rodriguez, M., Cáceres, J. Mauleón, S. ; Pallisa, E. ; Majó, J. ; Martinez-Rodriguez, M. ; Cáceres, J. Lobetti, et al. ... PATTERN blurring of vessels air bronchogram silhouette sign lobar sign Thoracic radiographs are routinely used in dogs and cats with respiratory disease, but their interpretation remains challenging. Berry, et al. Table 2. 5. b. mass: > 3 cm. Two lateral views, or ideally 3 thoracic views, are extremely important, as a partial collapse of pulmonary parenchyma in dependent portions of the thorax will obscure pulmonary nodules. Selected differential diagnoses for bronchial pulmonary patterns. Your cat can be exposed to a variety of things in the environment that can adversely affect his health. The reasons why the pulmonary parenchyma is difficult to evaluate is the fact that many different diseases can have a similar appearance, and there is a large degree of overlap of radiographic manifestation of diseases. c. miliary nodules: multiple small nodules, 2-3 mm in size Table 4. 4. Felis ISSN 2398-2950. 10. A variety of fungi thrive in our soil and water sources that can cause fungal infections of the lung in cats. When the chest radiograph shows a clear pattern of ILD or ALD, one can render a differential diagnosis on the basis of the pattern of parenchymal disease (Table 3.1). Erlotinib was stopped, and chemotherapy with cisplatin-pemetrexed and bevacizumab was introduced. When a cat breathes air in through its nose or mouth, the air travels down the trachea, which divides into the tubes known as the right and left bronchi, then into the smaller airways called bronchioles in the lungs. The most common entities with this pattern are miliary tuberculosis, pneumoconiosis, sarcoidosis, metastases, and hypersensitivity pneumonia. Neither had additional advanced respiratory diagnostics to characterize lesions; thus, they remain a presumptive inhalant toxin-induced ILD (Young et al., 2007). Rather than agonizing over how to name the radiographic appearance of the lungs, the observer should rather focus on the next step in the diagnostic workup. / Mauleón, S.; Pallisa, E.; Majó, J.; Martinez-Rodriguez, M.; Cáceres, J.; Andreu Soriano, Jorge. Radiographic signs: 1. relatively circumscribed nodule/mass. The rash is located on the dorsal side and does not seem to cause any distress, moderate itching. Lung Disease The most important question to ask yourself is: Is the lung too opaque or too lucent? Granulomatous form of PIE. Miliary tuberculosis (TB) is the widespread dissemination of Mycobacterium tuberculosis (see the image below) via hematogenous spread. BSAVA manual of canine and feline thoracic imaging. Selected differential diagnoses for alveolar pulmonary pattern based on distribution.3-6, Pneumonia, hemorrhage, neoplasia, lung lobe torsion, Unilateral with mediastinal shift to the same side, Contusions/hemorrhage, cardiogenic edema (cat), neoplasia, PIE, infectious (heartworm disease), thromboembolic disease, A bronchial pattern is an abnormal lung opacity caused by peribronchial cellular, fluid and fibrotic infiltration, or bronchial mucosal and submucosal thickening (chronic bronchitis). A ground glass lung result from a CT scan is a non-specific finding that describes an area characterized by a small increase in lung density, explains the National Institutes of Health. Those who are immunocompromised are especially at risk, because their immune systems can … D'Anjou, et al. In one cat, patchy fat-attenuating areas in the consolidated lung … What is a miliary interstitial pattern? This article reviews the high-resolution computed tomography imaging features of miliary pattern, a characteristic radiologic manifestation of diffuse micronodular lung disease. Most symptoms are related to the respiratory system, but in cases of metastasisthe symptoms vary depending upon the location of the metastasis in the body. Pulmonary lymphoma. Its name comes from a distinctive pattern seen on a chest radiograph of many tiny spots distributed throughout the lung fields with the appearance similar to millet seeds—thus the term "miliary" tuberculosis. A bronchial pattern on radiographs indicates a condition that involves the airways. 2008;242-260. We expose the most common entities. should be noted. J Small Anim Pract 2009; 50: 9-14. Following are some of the symptoms seen in patients with lung adenocarcinoma: 1. J Vet Int Med 2006; 20: 508-515. 471-480. Care should be taken not to confuse pulmonary nodules with osseous metaplasia, end-on pulmonary vessels and extrathoracic structures such as skin nodules or nipples (use nipple markers or barium on extrathoracic nodules to clarify). If fungal spores rise to critical levels, your cat can become sick. 2. Chest x-ray examination revealed a miliary interstitial nodular pattern in both lung fields. An unstructured interstitial pattern is caused by a collection of fluid, cells or fibrin within the connective tissue framework of the lung, between the alveoli and around vessels and airways. 7. The symptoms can be acute or present for several months. author = "S. Maule{\'o}n and E. Pallisa and J. Maj{\'o} and M. Martinez-Rodriguez and J. Often, a mixture of pulmonary patterns is present, and in those cases it is most efficacious to determine the predominant pattern as it will best define the source of the problem. According to the distribution of the nodules in relation to the secondary lobule, high-resolution computed tomography findings divide miliary patterns into 3 groups: centrilobular, perilymphatic, and random presentation. Minor improvement of the radiographic lung pattern in the follow-up studies was seen in two cats, and a miliary ‘sponge-like’ mineralised pattern appeared in the previously affected lung lobes months to years after the diagnosis. Pain 2. Diffuse interstitial lung pattern This pattern consists of small fibres, military nodules or a combination of both. journal = "Current Problems in Diagnostic Radiology", Mauleón, S, Pallisa, E, Majó, J, Martinez-Rodriguez, M, Cáceres, J, Mauleón S, Pallisa E, Majó J, Martinez-Rodriguez M, Cáceres J. According to the distribution of the nodules in relation to the secondary lobule, high-resolution computed tomography findings divide miliary patterns into 3 groups: centrilobular, perilymphatic, and random presentation. It can be a subtle pattern to recognize, so lets look at some of the features. If the lung are diffusely or focally too opaque then use the pattern system (below). In order to subdivide pathology of the interstitial space, interstitial pulmonary pattern are further divided into unstructured and nodular interstitial pattern. Aggregations of cells in the supportive lung tissues result in a nodular pattern. 1.Chest radiograph. Nevertheless, the pulmonary pattern model, if used appropriately, is a valuable diagnostic tool. Read the German translation: Interpretation der Lungenmuster beim Hund und bei der Katze. title = "Miliary lung disease revisited". 12. Nemanic, et al. doi = "https://doi.org/10.1067/mdr.2002.127634". J Vet Emerg Crit Care 2009; 19: 30-52. According to the distribution of the nodules in relation to the secondary lobule, high-resolution computed tomography findings divide miliary patterns into 3 groups: centrilobular, perilymphatic, and random presentation. Miliary granulomata (eg, fungal [not endemic in the UK] or tuberculous). GodfreyD. You see multiple, small nodules less than 5mm in diameter. A NUMBER of technical factors and incidental anatomical and physiological variations can mimic or mask pathology of the lung, while diseases of different aetiologies may present with a similar radiographic appearance, all of which can often make diagnosis of lung disease challenging. 11. abstract = "This article reviews the high-resolution computed tomography imaging features of miliary pattern, a characteristic radiologic manifestation of diffuse micronodular lung disease. vet., DECVDI, DACVR. @article{c8634519867246c0bbbafde6a2524f2a. 6.

A conundrum arises when widespread small opacities are difficult to categorize into one group or the other on chest radiography, or when ILD and ALD are both present. Suter, et al. A total collapse of the alveoli (atelectasis) leads to a similar appearance. It is produced by a change in size, shape or number of pulmonary vessels. There are 4 pulmonary patterns described.
