Sarcoidosis is an additional cause of a mosaic GGOs due to the formation of granulomas in interstitial areas. This may coexist with granulomatosis with polyangiitis, leading to diffuse areas of increased attenuation with ground-glass appearance. [6]
High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung; Transbronchial biopsy: proliferation of pulmonary neuroendocrine cells; Serum markers: elevated serum chromogranin A levels
Bronchiolitis obliterans results in worsening shortness of breath, wheezing, and a dry cough.The symptoms can start gradually, or severe symptoms can occur suddenly. [9] [10] These symptoms represent an obstructive pattern that is non-reversible with bronchodilator therapy, and need to be related to various lung insults. [11]
Air trapping, also called gas trapping, is an abnormal retention of air in the lungs where it is difficult to exhale completely. [1] It is observed in obstructive lung diseases such as asthma, bronchiolitis obliterans syndrome and chronic obstructive pulmonary diseases such as emphysema and chronic bronchitis.
The doctors and nurses didn’t believe Tomisa Starr was having trouble breathing. Two years ago, Starr, 61, of Sacramento, California, was in the hospital for a spike in her blood pressure.
The non-fibrotic form is typically characterized by ground glass opacities, mosaic attenuation, ill-defined centrilobular nodules (<5 mm), and air trapping. [12] The fibrotic form is typically characterized by irregular linear opacities/coarse reticulations, traction bronchiectasis , and honeycombing , patchy ground-glass attenuation ...
Two widely touted Alzheimer’s drugs have been shown to enable patients to remain in their homes for longer periods of time. Those medications, however, are not without their risks and side effects.
The new study, which was published in JAMA Psychiatry, could result in a future treatment for the more than 28 million American adults who struggle with alcohol-use disorder (AUD). Here’s what ...
