A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. [1] Pulmonary infiltrates are associated with pneumonia, tuberculosis, [citation needed] and sarcoidosis. [2] Pulmonary infiltrates can be observed on a chest radiograph. [citation needed]
The original published definition read as: "Any extended, finely granular pattern of pulmonary opacity within which normal anatomic details are partly obscured; from a fancied resemblance to etched or abraded glass." [23] It was again included in an updated glossary by the Fleischner Society in 2008 with a more detailed definition. [24]
In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy. [1] However, lesions may appear anywhere in the lungs. In HIV and other immunosuppressed persons, any abnormality may indicate TB or the chest X-ray may even appear entirely normal. [1]
Infiltration is the diffusion or accumulation (in a tissue or cells) of foreign substances in amounts excess of the normal. The material collected in those tissues or cells is called infiltrate . Definitions of infiltration
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. Chronic Kerley B lines may be caused by fibrosis or hemosiderin deposition caused by recurrent pulmonary edema.
Bat wing appearance is a radiologic sign referring to bilateral perihilar lung shadowing seen in frontal chest X-ray and in chest CT. [1] [2] The most common reason for bat wing appearance is the accumulation of oedema fluid in the lungs. [3] The batwing sign is symmetrical, usually showing ground glass appearance and spares the lung cortices. [4]
bilateral pulmonary infiltrates fibrocystic sarcoidosis typically with upward hilar retraction, cystic and bullous changes Although people with stage 1 radiographs tend to have the acute or subacute, reversible form of the disease, those with stages 2 and 3 often have the chronic, progressive disease; these patterns do not represent consecutive ...
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [ 2 ] (swelling or hardening of normally soft tissue) of a normally aerated lung.
