It occurs most often in infants and young children [1] but also has been reported in adults. [2] In a retrospective review of 204 children with lung tumors, pleuropulmonary blastoma and carcinoid tumor were the most common primary tumors (83% of the 204 children had secondary tumors spread from cancers elsewhere in the body). [ 1 ]
They occur most often as solitary, infratentorial lesions in young children. [3] In contrast, lesions are most often supratentorial in adults. [3] Pulmonary tuberculomas are among the most common benign nodules, with 5%-24% of all resected nodules being of tuberculous origin. [21]
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.
The cannonball sign is a radiological term used to describe the presence of multiple, well-circumscribed, round opacities seen on X-ray or CT imaging, typically in the lungs. [1] This finding is most commonly associated with hematogenous metastases, where malignant cells spread to the lungs via the bloodstream, forming discrete nodules that ...
It’s important to pay attention to the signs of lung disease and any symptoms that indicate your lungs might not be healthy, as early detection can go a long way in helping to manage and treat ...
3. Nodule with poorly defined margins - Round density within the lung parenchyma, also called a tuberculoma. Nodules included in this category are those with margins that are indistinct or poorly defined (tree-in-bud sign [3]). The surrounding haziness can be either subtle or readily apparent and suggests coexisting airspace consolidation.
Caplan syndrome is a nodular condition of the lung occurring in dust-exposed persons with either a history of rheumatoid arthritis (RA) or who subsequently develop RA within the following 5–10 years. [3] The nodules in the lung typically occur bilaterally and peripherally, on a background of simple coal workers' pneumoconiosis. There are ...
Side effects on the lungs can be very varied, and can include signs and symptoms that are either clinical, or radiological (i.e., seen on chest X-ray or CT), or both.They can include lung inflammation (pneumonitis), secondary (in this context, indirectly caused) lung infection (), lung fibrosis, organising pneumonia (bronchiolitis obliterans organising pneumonia, BOOP), ARDS (acute respiratory ...
