Brain stone

Brain stones, also known as cerebral calculi, refers to large intracranial calcifications that may be solitary or multiple.

Clinical presentation

If symptomatic, patients most commonly present with seizures.

Pathology

Localization of brain stones can help narrow the underlying etiology but the causes are numerous :

• intra-axial
  • calcifying tumors, e.g. oligodendrogliomas
  • vascular, e.g. cavernous malformations, arteriovenous malformations, aneurysms
  • infectious, e.g. congenital TORCH infections, tuberculosis, neurocysticercosis
  • congenital, e.g. Sturge-Weber syndrome, tuberous sclerosis, intracranial lipomas
  • metabolic, e.g. Fahr disease, hyper/hypoparathyroidism, pseudohypoparathyroidism
• extra-axial
  • meningiomas
  • dural osteomas
  • calcifying tumors, e.g. craniopharyngiomas
• intra- or extra-axial
  • calcifying pseudoneoplasms of the neuraxis (CAPNON)
