-
-
- Meningiomas are benign, slow-growing tumors, classified as brain tumors,
- but actually growing in the three protective membranes that surround the
- brain (meninges). Sometimes they cause thickening or thinning of adjoining
- skull bones. Meningiomas do not spread to other areas of the body.
-
- Symptoms
-
- Symptoms of Meningioma vary according to the size and location of the tumor.
-
- FRONTAL TUMORS:
- These type of tumors can produce progressive weakness on one side of the
- body or in a localized area such as a leg. They can also cause seizures
- that may be limited to one area (focal), or generalized. Mental changes may
- also occur.
-
- Seizures are caused by a disturbance in the electrical activity of the
- brain. They are usually sudden, brief attacks of altered consciousness,
- unusual muscle movements, sensations, and/or behavior. The patient with
- seizures may fall, experience jerky movements, appear to be in a daze or
- asleep. A focal seizure is localized in one part of the body. (For more
- information, choose "Epilepsy" as your search term in the Rare Disease
- database).
-
- Mental changes may include drowsiness, listlessness, dullness, or
- personality changes.
-
- If the tumor is in the dominant hemisphere, which is the left side of
- the brain for right handed persons, it can produce speech difficulties
- (aphasia). Frontal lobe tumors can also produce loss of sense of smell,
- blurred or double vision, and loss of bladder control (incontinence or
- sudden, unexpected urination).
-
- TEMPORAL TUMORS:
- Temporal tumors, particularly in the non-dominant hemisphere, usually
- cause no symptoms other than seizures. However, some patients loose the
- ability to recognize and name objects (anomia) if the tumor is in the
- dominant hemisphere.
-
- PARIETAL TUMORS:
- Meningiomas over the parietal lobe, which lies behind the frontal lobe,
- may produce either generalized seizures or focal sensory seizures which are
- characterized by a strange sensation (paresthesia) in a particular part of
- the body. The inability to identify an object by touching it
- (astereognosis) can also be caused by meningiomas of the parietal lobe.
-
- The most common symptom associated with brain tumors is headache.
- However, not all tumors cause headaches.
-
- Causes
-
- The cause of Meningioma is unknown. Meningiomas usually develop from cell
- clusters associated with arachnoidal villi.
-
- Affected Population
-
- Meningiomas most frequently occur in middle-aged persons. They are more
- common in women than in men by a ratio of 3:2. These types of tumors are
- rare in childhood, and they seldom affect black people in the United States.
-
- Therapies: Standard
-
- Many meningiomas can be completely removed surgically. Some, due to their
- location, can only be partially removed. In these areas of the brain,
- complete removal would carry the risk of damaging a major artery or of
- destroying a part of the brain. However, even partial removal should
- provide some relief from symptoms. Because meningiomas grow so slowly, it
- could be many years before further surgery may be necessary. Radiation and
- chemotherapy are usually not used to treat meningiomas.
-
- If the patient with Meningioma has muscle weakness, coordination
- problems, or speech impairment, physical, occupational, or speech therapy
- may be helpful. Complete recovery from symptoms is possible after surgery.
