Meningioma seen at autopsy, as a tumor of the dura mater extending into the cranial cavity, and can be detached from the bone along with the rest of the dura mater. Small tumors (e.g., < 2.0 cm) usually are incidental findings at autopsy without having caused symptoms. Larger tumors may cause symptoms, depending on the size and location.
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.

Cutaneous meningioma, also known as heterotopic meningeal tissue, and rudimentary meningocele [1] is a developmental defect, and results from the presence of meningocytes outside the calvarium. [ 2 ] : 622
The metastatic tumor cells grow either attached to the pia mater covering the brain and spinal cord or floating unattached to the subarachnoid space. [7] Tumors of diverse origins and hematologic cancers may spread to this space. [5] Some patients can develop a leptomeningeal tumor while receiving chemotherapy for their primary tumor.

A tumor growing from the meninges is referred to as a meningioma. Most meningiomas grow from the arachnoid mater inward applying pressure on the pia mater and therefore the brain or spinal cord. While meningiomas make up 20% of primary brain tumors and 12% of spinal cord tumors, 90% of these tumors are benign.
Dural tail sign seen associated with a meningioma. The dural tail sign (also known as "dural thickening", "flare sign", or "meningeal sign") is a radiological finding observed in magnetic resonance imaging (MRI) studies of the brain that refers to a thickening of the dura mater immediately adjacent to a mass lesion, such as a brain tumor.
