Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs. It is typically defined as an area of hazy opacification (x-ray) or increased attenuation (CT) due to air displacement by fluid, airway collapse, fibrosis , or a neoplastic process . [ 1 ]
In general, lung cysts were larger and more numerous in women than in men. [135] In a further retrospective study of women with TSC who underwent CT scanning to detect LAM, 25% of those in their 20s had lung cysts whereas 80% of women in their 40s were affected, suggesting that the development of LAM is age dependent at least in tuberous ...
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]
Acute presentation may reveal poorly defined a micro-nodular interstitial pattern and ground-glass opacities in the lower and mid lung zones. In addition to this, subacute presentations may show reticular nodular opacities in mid-to-lower lung zones. [1] Chronic forms may show fibrotic changes and appear like Idiopathic pulmonary fibrosis. [3]
Small, irregular opacities are classified by width as s, t, or u (same respective sizes as for small, rounded opacities). Lung Zones: Each lung is mentally subdivided by the reader into 3 evenly spaced zones: upper, middle, and lower. The zones in which the small parenchymal opacities appear are recorded.
