External meningioma is a common intracranial tumor that grows relatively slowly, but can still cause great distress to patients. Understanding the symptoms and methods of external meningioma is crucial for both the patient and the doctor.
1. Symptoms of external meningioma.
Symptoms of external meningioma vary depending on the size, location, and growth rate of the tumor, but here are some common symptoms:
1. Headache: Headache is one of the most common symptoms of external meningioma, which usually manifests as persistent dull pain or throbbing pain. The location and nature of the headache depends on the location of the tumor and how it grows.
2. Visual impairment: Visual impairment is also a common symptom of external meningioma, including vision loss, visual field defects, diplopia, etc. These symptoms are usually caused by a tumor pressing on the optic nerve or visual center.
3. Olfactory disorder: Olfactory disorder is also one of the symptoms of external meningioma, which is manifested as loss or loss of smell. This is usually caused by the tumor pressing on the olfactory nerve.
4. Hearing impairment: Hearing impairment is also one of the symptoms of external meningioma, which is manifested as hearing loss or loss. This is usually caused by a tumor pressing on the auditory nerve.
5. Motor and sensory disorders: Motor and sensory disorders are also one of the symptoms of external meningioma, which are manifested as limb weakness, numbness, involuntary movements, etc. This is usually due to the tumor pressing on the motor and sensory centers.
6. Psychiatric symptoms: Psychiatric symptoms are also one of the symptoms of external meningioma, which are manifested as memory loss, inattention, personality changes, etc. This is usually caused by a tumor pressing on the frontal lobe of the brain.
Second, the best method of external meningioma.
The most important methods for external meningioma include surgical resection, radiotherapy, and chemotherapy. **The choice of method depends on factors such as the size, location, and growth rate of the tumor, as well as the patient's age, physical condition, and comorbidities.
1. Surgical resection: Surgical resection is one of the main methods for external meningioma. Surgery to remove the tumor completely can effectively alleviate the patient's symptoms and prolong the survival time. The type and difficulty of surgery depends on factors such as the size, location, and growth of the tumor.
2. Radiotherapy: Radiotherapy is another common method for external meningioma. By irradiating the tumor, the tumour can shrink and relieve symptoms. Radiation therapy is usually used for tumors that cannot be removed surgically or that remain after surgery.
3. Chemotherapy: Chemotherapy is another method for external meningioma, but it is usually not the first choice. Chemotherapy drugs are transmitted through the bloodstream to the tumor site and can kill tumor cells and inhibit their growth. Chemotherapy is usually given to malignant external meningiomas or tumors that cannot be removed surgically.
