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 ]
2. Discrete nodule(s) without calcification—One or more nodular densities with distinct borders and without any surrounding airspace opacification. Nodules are generally round or have rounded edges. These features allow them to be distinguished from infiltrates or airspace opacities. To be included here, these nodules must be noncalcified.
Small nodular opacities occur in up to 50% of patients and large nodules in 15%. 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.
Worms and other internal parasites can be treated easily but are some of the most common problems seen in dogs. Some of the internal parasites that cause diarrhea and loose stools in puppies ...
Echinococcus is a tapeworm that most commonly infects dogs; people become infected by ingesting food or water that contains Echinococcus eggs. This results in cysts forming in the body, most commonly in the liver, but lung involvement is seen in 10-30% of cases. The cysts in the lung sometimes look like cavities on imaging. [7]
The dog then causes further trauma to the skin by itching and rubbing at the area, leading to a secondary bacterial infection." Acute moist dermatitis: Symptoms A patch of moist, inflamed skin ...
In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. [1] The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles, the smallest airway passages in the lung.
Arthritis: When senior dogs develop changes in their vertebral bones, their spine can be pressed upon, and they can display the type of changes in the back legs that you describe.
