What does bronchiectasis look like on a CT?
What does bronchiectasis look like on a CT?
A radiologist will associate bronchiectasis with the typical chest computed tomography (CT) scan features, consisting of an abnormally widened and thickened airway with an irregular wall, lack of tapering and/or visibility of the airway in the periphery of the lung [2].
What is tram track calcification?
Thin linear calcifications may get deposited in the peripheral renal cortex suggestive of cortical necrosis due to a vascular insult (vasculitis), and rarely due to glomerulonephritis. This pattern of calcification has also been referred to as the “tramline” or “railroad track” sign.
What is meant by tram track?
Filters. The track on which a tram runs; the tramway. noun.
What is signet ring bronchiectasis?
The signet ring sign is seen in bronchiectasis when the dilated bronchus and accompanying pulmonary artery branch are seen in cross-section. The bronchus and artery should be the same size, whereas in bronchiectasis, the bronchus is markedly dilated.
Can you see bronchiectasis on a CT scan?
A CT scan may reveal dilated, thickened airways, which are commonly found in bronchiectasis.
What are the three types of bronchiectasis?
Three basic morphologic types of bronchiectasis that are recognized at CT are cylindrical, varicose, and cystic (Fig 2), and many patients have a combination of these three classic types.
What is leptomeningeal Angioma?
This abnormality, which is called leptomeningeal angioma, can affect one or both sides of the brain and impair blood flow in the brain and lead to loss of brain tissue (atrophy) and deposits of calcium (calcification) in the brain below the angioma.
Is tram a train?
Tram vehicles are usually lighter and shorter than main line and rapid transit trains. Trams are now commonly included in the wider term “light rail”, which also includes grade-separated systems. Some trams, known as tram-trains, may have segments that run on mainline railway tracks, similar to interurban systems.
What are tram tracks made from?
Like standard rail tracks, tram tracks consist of two parallel steel rails. Tram rails can be placed on several surfaces, such as with standard rails on sleepers like railway tracks, or with grooved rails on concrete sleepers into street surfaces (pavement) for street running.
In which disease signet ring is found?
signet
Signet ring cells are present in 3% of cases of acinar adenocarcinoma, but the diagnosis of signet ring cell carcinoma requires that 25% or more of the tumor be composed of signet ring cells; some authors require 50% (Fig. 9.41). Tumor cells show distinctive nuclear displacement by clear cytoplasm.
Does bronchiectasis cause mucus in throat?
The most common symptom of bronchiectasis is a persistent cough that brings up a large amount of phlegm on a daily basis. The phlegm can be clear, pale yellow or yellow-greenish in colour. Some people may only occasionally cough up small amounts of phlegm, or none at all.
