Corpora arenacea

Brain sand
Latin Corpora arenacea
Code TH H3.
Anatomical terminology

Corpora arenacea (or brain sand) are age, so the pineal gland becomes increasingly visible on X-rays over time, usually by the third or fourth decade. They are sometimes used as anatomical landmarks in radiological examinations.

Chemical analysis shows that they are composed of calcium phosphate, calcium carbonate, magnesium phosphate, and ammonium phosphate.[1] Recently, calcite deposits have been described as well.[2]
