Body
was changed:
A burnt-out meningioma is a term used to denote a meningioma which has become completely calcified/ossified 1. The term refers to the usually indolent behaviour, as these tumours rarely seem to grow.
Most burnt out meningiomas are likely to be psammomatous meningiomas, as these are far more common than the other heavily calcified variety, metaplastic osseous meningioma. In addition to the abundant psammoma bodies, these tumours are fibrotic with few tumour cells.
Radiographic features
Burnt-out meningiomas appear as calcified extra-axial masses without enhancing component.
Differential diagnosis
-
inner-table osteoma of the skull2
ivory-density
directly attached to the skull by a bony stalk (mushroom shaped)
-
very rare
often not attached to dura
