Optic nerve sheath meningiomas (ONSM) are rare benign tumors of the optic nerve. 60–70% of cases occur in middle age females, and is more common in older adults (mean age 44.7 years). It is also seen in children, but this is rare. The tumors grow from cells that surround the optic nerve, and as the tumor grows, it compresses the optic nerve.
As with any type of tumor, brain tumors are an abnormal growth of cells, the number of which will determine, in part, the overall size of the tumor. In the case of benign brain tumors, these cells ...
These tentacles intermingle with healthy brain cells, making complete surgical removal difficult. However, they are low-grade tumors, with a slow rate of growth, so patients commonly survive longer than those with otherwise similar types of brain tumours, such as glioblastoma multiforme. [1]
The signs and symptoms of brain tumors are broad. People may experience symptoms regardless of whether the tumor is benign (not cancerous) or cancerous. [13] Primary and secondary brain tumors present with similar symptoms, depending on the location, size, and rate of growth of the tumor. [14]
A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [2]
A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are cancerous but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
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]
It should be remembered that these symptoms also are prevalent in many other illnesses not associated with ependymoma. [citation needed] About 10% of ependymomas are benign myxopapillary ependymoma (MPE). [7] MPE is a localized and slow-growing low-grade tumor, which originates almost exclusively from the lumbosacral nervous tissue of young ...
