The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT ...
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] Paragonimus westermani, also called the lung fluke, is a flatworm which is transmitted by eating freshwater crabs or crayfish containing metacercaria (the ...
AAH is a pre-malignant cause of nodular GGO and is more commonly associated with lower attenuation on CT and smaller nodule size (<10 mm) compared to adenocarcinoma. [10] In addition, AAH often lacks the solid features and spiculated appearance that are often associated with malignant growths. [ 9 ]
This leads to the accumulation of cellular debris within the lungs. This leads to consolidation or solidification, terms used for macroscopic or radiologic appearance of the lungs affected by pneumonia. Bacterial pneumonia is mainly classified into lobar and diffuse depending on the degree of lung irritation or damage. [4]
Typically, an area of white lung is seen on a standard X-ray. [5] Consolidated tissue is more radio-opaque than normally aerated lung parenchyma, so that it is clearly demonstrable in radiography and on CT scans. Consolidation is often a middle-to-late stage feature/complication in pulmonary infections.
It leads to an appreciable mass that can be ... an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and ... 10.1111/j .1447 ...
It also includes lung manifestations of autoimmune diseases such as Sjögren syndrome or rheumatoid arthritis. [ 3 ] [ 4 ] Histopathologic studies have shown that the tree-in-bud pattern is caused by demarcation of the normally invisible branching course of the peripheral airways, which usually results from bronchioles being plugged or blocked ...
