Depending on the location of Meningioma it grows slowly and reaches a rather large size before any symptoms are apparent. Some Meningiomas grow faster compared to the benign ones and may have abrupt growth spurts. The growth rate of a Meningioma cannot be predicted nor can one be certain of how long a particular tumor was growing prior to its diagnosis. Meningiomas generally occur in one site though in some cases several tumors may grow concurrently in various parts of the brain and spinal cord. In cases of multiple Meningiomas more than one type of treatment may be required. The symptoms of Meningioma may vary and appropriate treatment depends on where it is located. Some of the Meningioma symptoms include seizures, headaches, arm or leg weakness, or vision loss. Often patients have understated symptoms long before the diagnosis of Meningioma.
The various factors that predispose people into contracting Meningioma include exposure to radiation, and genetic disorders like neurofibromatosis. Some suggests the role of viruses in the cause of Meningioma, although this has not been substantiated at this point. The chances of recovering are mote positive in the younger patients than the older ones. Some of the tests used to diagnose the symptoms of this disease include enhanced CT and/or MRI (magnetic resonance imaging) scans. In cases of Meningioma an MRI scan is preferred though CT is useful in determining whether the tumor has invaded the bone, or how hard it has become. The survival rate is higher in case of Atypical Meningiomas followed by benign and malignant Meningioma.
