Dural osteoma

Last revised by Yaïr Glick on 29 Nov 2023

Dural osteomas are a cause of focal intracranial calcification (colloquially known as "brain stones"). They are difficult to differentiate from ossified "burnt out" meningiomas and ossification of the falx. Some reports are actually contradictory 1,4, suggesting that at least some lesions have been misclassified. 

Rarely, intracranial osteomas are identified without a dural attachment 3
