Mineral balance

• Dystrophic calcification, without a systemic mineral imbalance.
• Metastatic calcification, a systemic elevation of calcium levels in the blood and all tissues.

Location

• Skeletal calcification
• Extraskeletal calcification
  • e.g. Calciphylaxis
• 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.

What is a stub?

A stub is an article containing only a few sentences of text which is too short to provide encyclopedic coverage of a subject.

How is a stub identified?

• If possible, try to find the most appropriate stub template for the article. A full list can be found at Wikipedia:WikiProject Stub sorting/Stub types.
• Two or more different stub templates may be used, if necessary.
• Place a stub template at the very end of the article, after the "External links" section, any navigation templates, and the category tags. As usual, templates are added by including their name inside double curly brackets, e.g. {{stub}}.
