Meningioma, also known as meningeal tumor, is typically a slow-growing tumor that forms from the meninges, the membranous layers surrounding the brain and spinal cord. [1] Symptoms depend on the location and occur as a result of the tumor pressing on nearby tissue. [3] [6] Many cases never produce symptoms. [2]
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.

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.

All treatments for CNS tumors have significant risks and side-effects. In cases where tumors are slow growing and do not cause symptoms, it may be preferable to closely watch the patient's condition without any treatment, until new test results or symptoms indicate that the patient's condition has worsened. [17]
The study follows other research suggesting that an optical coherence tomography angiography (OCTA) scan could potentially help doctors detect signs of Alzheimer’s disease in the small veins ...
Researchers say MRI scans can help identify brain atrophy in people with Parkinson's and help predict the progression of the disease as well as what treatments might be most effective
A meningioma is a benign brain tumor. It originates from the arachnoid (not the dura), the tissue covering the brain and spinal cord lying deep to the dura. Meningiomas are much more common in females, and are more common after 50 years of age. Of all cranial meningiomas, about 20% of them are in the sphenoid wing.
