Multiple meningioma

More than two meningiomas that are not connected to each other in the skull are called multiple meningiomas, and about 400 cases have been reported in the literature so far. In 1822, Wishart first reported multiple meningiomas in a 21-year-old man who had both a thickened skull and bilateral neuromas. According to a modern point of view, this case should be a type II neurofibromatosis (Reck linghausenrsquo; s disease). About half of the patients reported in the literature were multiple meningiomas when first diagnosed, and about half of the patients were diagnosed after the first diagnosis Over time, one or more meningiomas were found elsewhere. Multiple meningioma is more common in the convex surface of the brain, scattered around a meningiomas, and can also occur at the base of the skull. Sometimes multiple meningiomas can be seen in the ventricle and the ventricle simultaneously, or they can occur on and off the screen at the same time. In addition, clinically common intracranial meningioma and acoustic neuroma or spinal canal meningioma coexist. Any type of meningiomas can be found in multiple meningiomas.
