Definitions related to meningioma:
-
A generally slow growing tumor attached to the dura mater. It is composed of neoplastic meningothelial (arachnoidal) cells. It typically occurs in adults, often women and it has a wide range of histopathological appearances. Of the various subtypes, meningothelial, fibrous and transitional meningiomas are the most common. Most meningiomas are WHO grade I tumors, and some are WHO grade II or III tumors. Most subtypes share a common clinical behavior, although some subtypes are more likely to recur and follow a more aggressive clinical course. (Adapted from WHO)NCI ThesaurusU.S. National Cancer Institute, 2021
-
A relatively common neoplasm of the CENTRAL NERVOUS SYSTEM that arises from arachnoidal cells. The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL.

A type of slow-growing tumor that forms in the meninges (thin layers of tissue that cover and protect the brain and spinal cord). Meningiomas usually occur in adults.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021

Meningiomas are benign tumors of the meninges that can compress adjacent brain tissue. Symptoms depend on the tumor�s location. Diagnosis is by MRI with contrast agent. Treatment may include excision, stereotactic radiosurgery, and sometimes radiation therapy.Merck & Co., Inc., 2020

Meningioma, the term coined by Harvey Cushing, refers to a set of tumors that arise contiguously to the meninges. .WebMD, 2019
-
A meningioma is a tumor that arises from the meninges - the membranes that surround your brain and spinal cord. Although not technically a brain tumor, it is included in this category because it may compress or squeeze the adjacent brain, nerves and vessels. Meningioma is the most common type of tumor that forms in the head.Mayo Foundation for Medical Education and Research
-
Meningioma s are tumors that originate in the meninges, the membranes that surround the brain and spinal cord. Most meningiomas are not cancerous (benign), though a minority of meningiomas can be classified as atypical or cancerous (malignant). Though rare, malignant meningiomas can be highly aggressive. However, even benign meningiomas...National Center for Advancing Translational Sciences

Meningiomas are one of the most common primary tumors of the cranial and spinal compartments. Estimates indicate they represent over 36% of primary brain tumors and 53.5% of all nonmalignant tumors. They are more frequent in women and are usually benign. They are sometimes atypical or malignant in nature.Athenahealth, Inc., 2019
