The most common benign coin lesion is a granuloma (inflammatory nodule), for example due to tuberculosis or a fungal infection, such as Coccidioidomycosis. [6] Other infectious causes include a lung abscess, pneumonia (including pneumocystis pneumonia) or rarely nocardial infection or worm infection (such as dirofilariasis or dog heartworm ...
The cuboidal cells within LAM lesions also react with a monoclonal antibody called HMB-45, developed against the premelanosomal protein gp100, an enzyme in the melanogenesis pathway. [107] This immunohistochemical marker is very useful diagnostically, because other smooth muscle-predominant lesions in the lung do not react with the antibody. [108]
Pneumonia can lead to the development of a lung abscess, [4] which is a pus-containing necrotic lesion of the lung parenchyma (lung tissue). [5] On CT scan of the chest, a lung abscess appears as an intermediate- or thick-walled cavity with or without an air-fluid level (a flat line separating the air in the cavity from the fluid). [ 4 ]
On radiological studies, thoracic splenic lesions are visualized using CT scans. Visualized lesions can be described as solitary or multiple nodules. The locations of the lesions are mostly in the lower left pleural space and/or splenic bed. Confirmation can be done using scintigraphy with 99mTc tagged heat-damaged red blood cells. [6]
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 ...
The skin is the second-most commonly affected organ after the lungs. [33] The most common lesions are erythema nodosum, plaques, maculopapular eruptions, subcutaneous nodules, and lupus pernio. [33] Treatment is not required, since the lesions usually resolve spontaneously in 2–4 weeks.
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
The terms above, when referring to sites other than the lungs, often imply fluid content. Lung cysts are seen in about 8% of the general population, with an increased prevalence in older people, and are not associated with emphysema. [5] They may be part of the aging changes of the lungs, and cause a slight decrease in their diffusing capacity. [5]
