Calcification is the process in which calcium salts build up in soft tissue, causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification.
Mineral balance
Location
- Skeletal calcification
- Extraskeletal calcification
- Brain (e.g. Fahr's syndrome)
Pattern
Patterns of calcifications may indicate pathological processes. Laminated appearance suggests granulomatous disease while popcorn calcification indicate hamartoma. Malignant lesions may have stippled or eccentric lesions.
