Ground-glass opacity is in contrast to consolidation, in which the pulmonary vascular markings are obscured. [3] [5] GGO can be used to describe both focal and diffuse areas of increased density. [5] Subtypes of GGOs include diffuse, nodular, centrilobular, mosaic, crazy paving, halo sign, and reversed halo sign. [6]
To confirm the diagnosis, a doctor may perform a lung biopsy using a bronchoscope. Many times, a larger specimen is needed and must be removed surgically. Plain chest radiography shows normal lung volumes, with characteristic patchy unilateral or bilateral consolidation. Small nodular opacities occur in up to 50% of patients and large nodules ...
Usual interstitial pneumonia (UIP) is a form of lung disease characterized by progressive scarring of both lungs. [1] The scarring (pulmonary fibrosis) involves the pulmonary interstitium (the supporting framework of the lung). UIP is thus classified as a form of interstitial lung disease.
It also includes lung manifestations of autoimmune diseases such as Sjögren syndrome or rheumatoid arthritis. [ 3 ] [ 4 ] Histopathologic studies have shown that the tree-in-bud pattern is caused by demarcation of the normally invisible branching course of the peripheral airways, which usually results from bronchioles being plugged or blocked ...
Pulmonary veno-occlusive disease can only be well diagnosed with a lung biopsy. CT scans may show characteristic findings such as ground-glass opacities in centrilobular distribution, and mediastinal lymphadenopathy , but these findings are non-specific and may be seen in other conditions.
Centrilobular emphysema, also called centriacinar emphysema, affects the centre of a pulmonary lobule (centrilobular) in the lung, the area around the terminal bronchiole and the first respiratory bronchiole, and can be seen on imaging as an area around the tip of the visible pulmonary artery. Centrilobular emphysema is the most common type ...
Clinical tests include chest radiography or (HRCT) which may show centrilobular nodular and ground-glass opacities with air-trapping in the middle and upper lobes of the lungs. Fibrosis may also be evident. Bronchoalveolar Lavage (BAL) findings coinciding with pneumonitis typically include a lymphocytosis with a low CD4:CD8 ratio. [7] [13]
lung injury of acute onset, within 1 week of an apparent clinical insult and with the progression of respiratory symptoms; bilateral opacities on chest imaging (chest radiograph or CT) not explained by other lung pathology (e.g. effusion, lobar/lung collapse, or nodules) respiratory failure not explained by heart failure or volume overload ...
