What is atypical meningiom?

Meningiomas are mening tumors, membranes that cover the brain and spinal cord. Most often they are benign meningiomas or meningiomas of grade I, which remain small and do not grow indefinitely as cancerous tumors. Atypical meningioma, also called meningioma of class II, is a meningal tumor that could be malignant and grew back after treatment or removal. Meningiom Grade III grows aggressively and threatens to compress adjacent brain tissue and bone attack. Even benign meningioma can be dangerous because of its proximity to the brain.

One of the most common forms of brain tumors, meningiomas is about 30 percent of all such cancers. The diagnosis of meningiomas is most often performed by displaying magnetic resonance (MRI). Patients who have symptoms will first undergo a neurological examination and then display the brain to determine whether they have a brain tumor. In asymptomatic patients, diagnosis is sometimes happening during the displaying of That brain has been asked for further medical complaintsst.

symptomatic patients often have atypical or malignant varieties. They report neurological symptoms such as headaches, seizures, loss of feeling, nausea, blurred vision and sensitivity to light. They can develop almost anywhere in the nervous system, but most meningiomas occur in the head, often near the brain stems, skull base, venous sinus or optical nerve.

atypical meningioma is more common in middle -aged or higher women and is rare in children; Spinal meningiomas are rarely found in men. They have faster growth speed than grade I tumors, but grow less speed than clearly malignant. Class I Meningiomas accounts for less than 10 percent of the total occurrence. Malignant Grade II cases are about 2 percent.

Scientists have associated the advent of maningiomas with mutation in the gene that encodes tumor-depressor protein. Severe innate mutations of this gene cause syndrome where patientsThey develop more benign tumors. Other mutations lead to a greater risk of benign or atypical meningioma. A small percentage of cases were associated with the hereditary form of illness; Most children who develop class II meningioms fall into this category. Meningiomas of grade II and III III in children are often relatively serious and quickly progress.

Atypical meningioma may require treatment to prevent further growth. Any tumor causing symptoms in the patient is usually treated as if it were malignant. Treatment includes surgical removal and monitoring of radiation therapy to kill the remaining tumor cells.

The decision on the treatment of tumor is considered to grow, current and future risks to brain tissue, age and health of the patient, and the possible consequences of surgery, such as infection or brain edema. Sometimes the shock of radiation and increase may be greater problems than the risk of a slowly growing tumor. For example, in older patients who do not have rapidly growing tumors, it is regular afterParting is often preferred as treatment because surgery can represent more life -threatening complications than tumors themselves. Class I rarely returns if it has been surgically removed, but atypical meningioma has a higher risk of recurrence.
