A lung nodule or pulmonary nodule is a relatively small focal density in the lung. 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 ...
For lung nodules, air bronchograms used to be associated with infectious causes of consolidation and, therefore to be benign. However, in the setting of a lung nodule, an air bronchogram is actually more frequent in malignant than in benign nodules. [1] [4] studied the tumour-bronchus relationship and described five types: [1]
Complications are not common but include infection, lung abscess, and bronchopleural fistula (a fistula between the pleural space and the bronchial tree). [4] A bronchopleural fistula results when there is a communication between the laceration, a bronchiole, and the pleura; it can cause air to leak into the pleural space despite the placement of a chest tube.

A lung nodule is a discrete opacity in the lung which may be caused by: Neoplasm: benign or malignant; Granuloma: tuberculosis; Infection: round pneumonia; Vascular: infarct, varix, granulomatosis with polyangiitis, rheumatoid arthritis; There are a number of features that are helpful in suggesting the diagnosis: rate of growth
The most frequent findings on a computed tomography (CT) of the chest are multiple primary nodules and/or masses, on a background of mosaic attenuation and airway wall thickening. [2] [9] The nodules have an indolent pattern of growth and are found throughout the lungs. The nodules are typically rounded and well-defined.
In the early 1960s, a relatively new chronic lung disease was being observed and described by physicians in Japan. In 1969, [31] the name "diffuse panbronchiolitis" was introduced to distinguish it from chronic bronchitis, emphysema, alveolitis, and other obstructive lung disease with inflammation. Between 1978 and 1980, the results of a ...

Parenchymal hamartoma of the lung. The surrounding lung falls away from the well-circumscribed mass, a typical feature of these lesions. The hamartoma shows a variegated yellow and white appearance, which corresponds respectively to fat and cartilage. About 5–8% of all solitary lung nodules and about 75% of all benign lung tumors, are ...
