Lung zone involvement and profusion increases with disease progression. In advanced cases of silicosis, large opacity (> 1 cm) occurs from coalescence of small opacities, particularly in the upper lung zones. With retraction of the lung tissue, there is compensatory emphysema. Enlargement of the hilum is common with chronic and accelerated ...
Metastatic calcification can occur widely throughout the body but principally affects the interstitial tissues of the vasculature, kidneys, lungs, and gastric mucosa. For the latter three, acid secretions or rapid changes in pH levels contribute to the formation of salts.
May have calcification; Non-progressive; After drugs, such as methysergide or bromocriptine: Diffuse; Possible interstitial pulmonary fibrosis; Cancer-related Primary cancer, mainly mesothelioma: Associated with asbestosis; Progressive thickening; Metastasis or invasion, mainly from lung cancer: Progressive; Nodular changes; Lung tumors
"Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not granulomatous. Similarly, radiologists often use the term granuloma when they see a calcified nodule on X-ray or CT scan of the chest. They make this assumption since granulomas usually contain calcium, although the cells that form a ...
Sometimes a hypodense central area is seen instead of calcification. [25] When considering other potential intracranial masses in a differential diagnosis, such as cysticercosis , pyogenic abscess, and neoplastic lesions, tuberculoma can be identified by its larger size (>2 cm), edema, and irregular border.
The ILO Classification system pertains to pulmonary parenchymal abnormalities (small and large opacities), pleural changes (pleural plaques, calcification, and diffuse pleural thickening) and other features associated, or sometimes confused, with occupational lung disease.
Dystrophic calcinosis cutis is the most prevalent kind of calcification on the skin. [2] The ectopic calcified mass usually consists of amorphous calcium phosphate and hydroxyapatite. [6] Dystrophic calcification is linked to a number of illnesses, such as infections, hereditary diseases, cutaneous neoplasms, and connective tissue diseases. [7]
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
