Wegener's is a collagen vascular disease with vasculitis involving the lung, kidney and sinuses. The HRCT - not shown - demonstrated a fine nodular appearance as a result of sarcoidosis. Sometimes Kerley B lines are visible. The main differential diagnosis of Kerley B lines is: interstitial edema in heart failure lymphangitis carcinomatosa. Semin Roentgenol. Here another case. Lymphangitis carcinomatosis also produces a reticular pattern.

    B, Second example with pneumonia of the right middle lobe (arrow). If pathology of similar density to that of the heart filled the right middle lobe, the right In general, the left heart border is adjacent to the lingula of the left upper lobe, the.

    posterior border of the heart +/- posterior left hemidiaphragm: left lower lobe; anterior right hemidiaphragm: right middle lobe; posterior right hemidiaphragm. increased density with ill-defined borders in the left lung; the heart This was an acute lobar pneumonia caused by Streptcoccus pneumoniae.
    A follow-up CXR shows resorption of most of the lung abnormalities.

    For lesions with a benign pattern of calcification, further testing is not necessary. This latter gravity-dependent phenomenon makes interpretation of cephalization on a portable film difficult. However, there can be significant hypertrophy or restrictive cardiomyopathy without any chamber enlargement. The mucus in the dilated bronchi looks like the fingers in a glove. The differential diagnostic list of multiple masses is very long.

    Here a chest x-ray of a large cavitating lung cancer, which started as a small mass.

    Sometimes the reticulation is more coarse like in this case of congestive heart failure. It is measured by dividing the maximal transverse cardiac silhouette by the maximal internal thoracic diameter using 0.

    The sparing of the periphery of the lung is attributed to a better lymphatic drainage in this area.

    The sign is commonly applied to the heart, aorta, chest wall, and diaphragm. lower lobes which cause an overlap and not an obliteration of the heart border. Therefore both the presence and absence of this sign is useful in the localization of pathology. This is caused by a pneumonia, can you determine which lobe the.

    1) Opacification of what part of the lung will silhouette the left heart border? 17) Pneumonia causes volume loss or collapse of the affected lung parenchyma. This diagnosis of a left-sided cardiac failure due to an acute ischemic cardiac insult is suggested on.

    A constant feature is loss of definition of the right heart border. Nosocomial pneumonia is the leading cause of death in the ICU patient .
    Atelectasis - collapse of a part of the lung due to a decrease in the amount of air in the alveoli resulting in volume loss and increased density.

    Etiologies include atherosclerotic disease, trauma, and, less commonly today, syphilitic aortitis. Philadelphia: W. Continue with the follow up films.

    Underlying lung diseases can cause variable and asymmetric appearances of pulmonary edema.

    SPN's are most commonly benign granulomas, while lesions larger than 3 cm are treated as malignancies until proven otherwise and are called masses. Notice the displacement of the mediastinum to the right. It demonstrates, that based on the x-ray alone, it is not certain which pattern we are looking at.

    Other causes of a false impression of cardiomegaly are the greater Left ventricular enlargement expands the left heart border on the PA view (Figure ) and. of focal intrapulmonary shunting such as pulmonary emboli and pneumonia.

    In radiology, the silhouette sign refers to the loss of normal borders between thoracic structures. It is usually caused by an intrathoracic radiopaque mass that touches the border of the heart or aorta.

    PRESENT.
    Radiologists use many terms to describe areas of decreased density or lucencies within the lung, like cyst, cavity, pneumatocele, emphysema, bulla, honeycombing, bleb etc.

    Despite the subjectivity, evaluation of pulmonary blood volume is an important part of the cardiovascular interpretation of the chest x-ray and should not be overlooked.

    In the differential diagnosis there is overlap between cavities and cysts. The increased heart size is usually what distinguishes between cardiogenic and non-cardiogenic. In this case there are some mass-like structures in the right lung. Boston: Butterworths; Multifocal Multifocal consolidations are also described as multifocal ill-defined opacities or densities.
