What is ossification of the lungs?
Pulmonary ossification refers to bone tissue formation (calcification in a collagen matrix), with or without marrow elements, in the lung parenchyma. While other organs can be affected by ectopic calcification and ossification, the lungs are particularly susceptible [1].
What is parenchymal calcification?
Parenchymal calcification of the kidneys may be defined as the deposition of calcium salts in the substance of the kidneys, in contradistinction to the forma- tion of gross stones in the renal pelvis.
What do you mean by calcification?
Calcification is a process in which calcium builds up in body tissue, causing the tissue to harden.
What are the symptoms of calcification in the lungs?
Lung granulomas and other growths in your lungs are usually identified when your doctor is looking for other respiratory problems. That means it’s important to report symptoms such as coughing, shortness of breath, and chest pain promptly to your doctor.
Where does calcification of the lung nodule occur?
Metastatic pulmonary calcification usually occurs in normal pulmonary parenchyma (alveolar walls, bronchi and blood vessel walls), the kidney and the stomach. Such calcification is secondary to abnormal calcium metabolism without any prior soft tissue damage.
Are there any lung cancers that are calcified?
The prevalence of calcified lung cancers identified on conventional chest radiographs is said to be 1%. Thus, calcification in PN does not guarantee benignity. [ 1, 3, 11 – 15] However, radiographs of resected of lung cancers specimens have shown calcific deposits in 16% specimens. [ 14]
Is there calcification in the alveolar ducts?
Calcification extended into the alveolar ducts, but there was no associated alveolar calcification in any of the sections obtained from the lung slices ( Fig. 3 ). Neither the larger elastic, nor the large to small muscular arteries contained calcific deposits.
Where does intrathoracic calcification occur in pulmonary disease?
Intrathoracic calcification is an important feature of pulmonary disease (Box 1-10). It is usually dystrophic (i.e., occurs in areas of necrosis). Less commonly, it is metastatic (i.e., related to hypercalcemia). Calcification may occur in focal lesions such as solitary pulmonary nodules (Fig. 1-51).
