Abstract
A meningioma is a usually slow-growing tumor that develops in the meninges, the protective layers around the brain and spinal cord. Most meningiomas are non-cancerous, but they can still cause symptoms such as headaches, vision problems, seizures, or weakness by pressing on nearby brain tissue. They are more common in older adults and women, and risk factors include prior radiation exposure and conditions such as neurofibromatosis type 2.
Diagnosis is typically made with imaging scans such as MRI, and treatment may involve observation, surgery, or radiation depending on the tumor's size and symptoms. This report describes a case in which preoperative endovascular embolization was used to reduce intraoperative blood loss prior to complete surgical excision of a hypervascular meningioma.
