The differential diagnosis for ground-glass opacities is broad. General etiologies include infections, interstitial lung diseases, pulmonary edema, pulmonary hemorrhage, and neoplasm. A correlation of imaging with a patient's clinical features is useful in narrowing the diagnosis. [6] [7] GGOs can be seen in normal lungs. Upon expiration there ...
There may be superimposed CT features such as mild ground-glass opacity, reticular pattern and pulmonary ossification. Probable UIP pattern: [4] Predominantly subpleural and basal; Often heterogenous distribution; Reticular pattern with peripheral traction bronchiectasis or bronchiolectasis; There may be mild ground-glass opacity; Indeterminate ...
It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage, but in interstitial lung disease, the repair process is disrupted, and the tissue around the air sacs (alveoli) becomes scarred and thickened.
On high resolution computed tomography, airspace consolidation with air bronchograms is present in more than 90% of patients, often with a lower zone predominance. A subpleural or peribronchiolar distribution is noted in up to 50% of patients. Ground glass appearance or hazy opacities associated with the consolidation are detected in most patients.
Desquamative interstitial pneumonia (DIP) is a type of idiopathic interstitial pneumonia featuring elevated numbers of macrophages within the alveoli of the lung. [1] DIP is a chronic disorder with an insidious onset. Its common symptoms include shortness of breath, coughing, fever, weakness, weight loss, and fatigue.
Winrevair was approved to treat pulmonary arterial hypertension (PAH), a progressive disorder caused by a constriction of arteries in the lungs, leading to symptoms such as shortness of breath ...
Mutations in the gene SLC34A2 [1] [2] result in loss of a key sodium, phosphate co-transporter (called Npt2b), known to be expressed in distal alveolar type II cells, as well as in the mammary gland, and to a lesser extent in intestine, kidney, skin, prostate and testes. As the disease progresses, the lung fields become progressively more dense ...
The halo sign is also understood as a region of ground-glass attenuation surrounding a pulmonary nodule on an X-ray computed tomography (CT scan) of the chest. It can be associated with hemorrhagic nodules , tumors , or inflammatory processes, but is most commonly known as an early radiographic sign of invasive pulmonary infection by the fungus ...
