Purpose To use ultrasonography (USG) for the evaluation of lung parenchyma in patients with sarcoidosis, andto compare the USG findings with the results of a high-resolution computerized tomography (HRCT) and pulmonary function test-carbon monoxide diffusion test (PFT-DLCO), which are commonly used methods in the evaluation of parenchymal involvement in sarcoidosis. Diffuse parenchymal lung diseases are disorders that affect the interstitial of the lung"the area around the lung’s air sacs. Most of the abnormalities will be observed in the upper lobes [5]: lymphatic micronodules visible particularly along the pleura or fissures, grouped into bunches (the galaxy sign), or along the bronchovascular bundles giving them an irregular appearance, fibrosis with central bronchovascular distortion, mediastinal lymphadenopathy, which may be calcified depending on the stage of the disease (egg-shell calcifications, differential diagnosis with silicosis). Surg. Organizing pneumonia represents about half of the reported parenchymal abnormalities in IBD patients, most reported cases have UC, and necrobiotic nodules are rarely seen.

Although pulmonary complications developing secondary to lung infections and involvement in ribs occur frequently in multiple myeloma (MM), involvement of the lung parenchyma is quite rare. CT of the lung parenchyma in restrictive disease may be beneficial to detect the earlier parenchymal changes in immunocompromised patients to allow early initiation of needed medical therapy. Lymphangitic metastases, however, cause greater septal thickening the underlying anatomy is called ground glass density. also characterized by small nodules and can look similar to sarcoidosis, However, pulmonary artery involvement in BD is not limited to PAA; the other main type of pulmonary artery involvement is pulmonary artery thrombus (PAT), with or without associated PAA. Clinical presentation is variable. Amongst these measures, PFTs provide the most precise measurement of disease severity, both in the cases of airway or lung parenchyma involvement.
