Oponiak

A rare, mostly benign, neoplastic disease characterized by a primary tumor of the meninges, usually located intracranially (~90%) but spinal meningiomas occur as well. Clinical symptoms relate to the location of the tumor and may include seizures, focal neurological deficits (sensory-motor or visual symptoms, cranial nerve dysfunction), vascular complications (occlusion of cerebral blood vessels, deep venous thrombosis, pulmonary embolism), chronically increased intracranial pressure neurocognitive impairment and/or loss of bladder/anus sphincter control.
