![](meningioma.gif)
- Meningiomas are frequent
primary tumors of the nervous system and can occur anywhere along the neuraxis,
including intracranial, spinal (gross pathology - below), intraventricular
and extracranial sites
- Spinal meningiomas form
only a small proportion of all meningiomas (12%) and are the second most common
spinal neoplasm following schwannomas
- Most meningiomas are
benign and do not invade the parenchyma, although malignant variants exist
(ex. anaplastic meningioma)
