This appearance is thought to result from the aggregation of a vast number of interstitial granulomas rather than representing a true alveolar process. Some authors have therefore applied a more appropriate term, pseudoalveolar sarcoidosis. Radiographic features CT. There can be large areas of pulmonary opacification ranging in diameter from 1 to 4 cm.

This lotus torus-like mass regressed spontaneously. This is the second reported case of pulmonary cavitary sarcoidosis with a 'lotus torus-like' appearance. Sarcoidosis is a systemic inflammatory disease with a predilection for the respiratory system. Although most patients enter remission and have good long-term outcomes, up to 20% develop fibrotic lung disease, whereby granulomatous inflammation evolves to pulmonary fibrosis. Sarcoidosis is a highly variable disease of unknown origin. The hallmark of sarcoidosis is the formation of nodules, or granulomas, in the lungs and other organs. We describe a rare case of bullous emphysema occurring in a young male with sarcoidosis.

The chest radiograph is normal (stage 0) in about 10% of patients who have biopsy-proven pulmonary sarcoidosis. Mediastinal lymph node enlargement is very common with sarcoidosis, occurring in 60% to 90% of patients at some stage in their disease. Less than half of patients with lymph node enlargement also show findings of lung disease on plain radiographs. A greater percentage of patients with lymph node enlargement show evidence of lung disease on CT. Stage 3 sarcoidosis with coarse reticulonodular pattern. There is no lymphadenopathy.

This distribution is typical of sarcoidosis. 39. Stage IV pulmonary sarcoidosis in a 62-year-old man.

Sarcoidosis is a disease that causes your immune system to overreact, which can lead to lung damage, skin rashes and eye disease. In this section you'll understand what sarcoidosis is, symptoms and risk factors of sarcoidosis, how it's treated and more.

Sarcoidosis is a non-caseating granulomatous multisystem disease with a wide range of clinical and radiographic manifestations. Individual systemic manifestations are discussed in respective articles: pulmonary and mediastinal manifestations The lung is the most commonly affected organ in sarcoidosis. Mediastinal lymph nodes (classically with eggshell calcification) are seen in 60-90% of cases. The 1-2-3 pattern of bilateral hilar and right paratracheal lymph node enlargement may be seen.

Reprinted from the Funda-mentals of Chest Radiology1 with permission from El-sevier. Sarcoidosis can be discovered by a chest x-ray taken for another purpose in an asymptomatic patient. Symptomatic patients The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases. Approximately 60 to 70% of patients with sarcoidosis have characteristic radiologic findings. In 25 to 30% of cases the radiologic findings are atypical. In 5 to 10% of patients the chest radiograph is normal.

Pulmonary sarcoidosis may manifest with various radiologic patterns: Bilateral hilar lymph node enlargement is the most common finding, followed by interstitial lung disease.

EpidemiologyFrom the limited case reports avail Although sarcoidosis commonly involves the lungs, it can affect virtually any organ in the body. Computed tomography (CT), magnetic resonance imaging, and positron emission tomography/CT are useful in the diagnosis of extrapulmonary sarcoidosis, but imaging features may overlap with those of other conditions.

Sarcoidosis is a systemic disorder of unknown cause with a wide variety of clinical and radiologic manifestations. The diagnosis is usually made on the basis of these manifestations supported by histologic findings. Systemic manifestations (eg, Löfgren syndrome, Heerfordt syndrome) are commonly seen at clinical examination.

Sarcoidosis is a systemic and chronic disease of unknown cause [1]. The characteristic histologic lesion, a noncaseating granuloma, has been described as affecting all organ systems, although they are most frequently seen affecting the lungs [2]. The imaging features of sarcoidosis are protean and can be shown with a variety of imaging techniques. 2013-03-01 SARCOIDOSIS vs SILICOSIS The CT scan, shows diffuse micronodular lung disease predominantly in the upper lobes with mediastinal widening consistent with mediastinal lymphadenopathy, dominant in the right paratracheal region and in the subcarinal region.
