Quick Summary:

• Meningioma is a mostly benign tumor that arises from the meninges which is the membranous tissue encasing the central nervous system (brain and spinal cord). The meninges consist of three layers, namely the outer layer (dura mater), the middle layer (arachnoid mater), and the inner layer (pia mater); together, they form the protective lining around the brain
• Meningiomas are rare and usually slow-growing tumors that are typically diagnosed in older individuals (60 years and above). The World Health Organization (WHO) classifies meningiomas based on their behavior as benign (grade I), atypical (grade II), and malignant (grade III) tumors. The grade and histologic subtype of the tumor is determined by the pathologist after examining a tissue biopsy of the tumor, under a microscope
• Angiomatous Meningioma is a relatively rare subtype of benign meningioma that mostly originates from the cerebellopontine angle location in the brain. It is categorized as a vascular tumor, meaning that it consists of abundant concentration of blood vessels visualized on a tissue biopsy. According to WHO classification, Angiomatous Meningiomas are grade I brain tumors, meaning they are the most benign of the brain tumors
• WHO grade I benign tumors are low-grade tumors that are slow-growing and not known to infiltrate into the surrounding tissues. These tumors also offer a very high chance for surgery to be curative, thus having the best prognosis amongst all brain tumors; long-term survivals are usually noted
• The cause of Angiomatous Meningioma is not well understood, but certain genetic abnormalities have been implicated. In general, the risk factors for meningioma may include ionized radiation exposure, hormonal factors in women, breast cancer history, and a family history of meningiomas
• The signs and symptoms depend on the size and location of the tumor and may include headaches, weakness in arms or legs, and vision and speech problems. Complications associated with the tumor include memory loss, personality changes, and seizures. Normally, there is a delay in diagnosing slow-growing and asymptomatic tumors, which may result in additional complications
• Once diagnosed, the treatments for Angiomatous Meningioma may include a combination of surgery, radiation therapy, and the administration of certain drugs to slow progression of the tumor, based on the healthcare provider’s assessment. The prognosis for individuals is generally good in a majority of cases, since the tumor is benign (WHO grade I tumor)
