normale intrakranielle Verkalkungen

Normal intracranial calcifications can be defined as all age-related physiologic and neurodegenerative calcifications that are unaccompanied by any evidence of disease and have no demonstrable pathological cause.

The most common sites include:

• pineal gland
  • seen in 2/3 of the adult population and increases with age
  • calcification over 1 cm in diameter or under nine years old may be suggestive of a neoplasm
• habenula
  • it has a central role in the regulation of the limbic system and is often calcified with a curvilinear pattern a few millimeters anterior to the pineal body in 15% of the adult population
• choroid plexus
  • a very common finding, usually in the atrial portions of the lateral ventricles (choroid glomus)
  • calcification in the third or fourth ventricle or patients less than nine years of age is uncommon
• basal ganglia
  • are usually incidental idiopathic findings that have an incidence of ~1% (range 0.3-1.5%) and increases with age
  • usually, demonstrate a faint punctuate or a coarse conglomerated symmetrical calcification pattern
  • see basal ganglia calcification for specific differential
• falx, dura mater or tentorium cerebelli
  • occur in ~10% of the elderly population
  • dural and tentorial calcifications are usually seen in a laminar pattern and can occur anywhere within the cranium
• petroclinoid ligaments
  • common age-related degeneration sites and usually have laminar or mildly nodular patterns
• superior sagittal sinus
  • common age-related degeneration sites and usually have laminar or mildly nodular patterns
• dentate nuclei of cerebellum
• hippocampus
