What Is an Atypical Meningioma?

Tumors growing in the skull are commonly known as brain tumors, including primary brain tumors that occur from the parenchyma of the brain and secondary brain tumors that metastasize to the skull from other parts of the body. Its etiology is unknown until now, and tumors occur from the brain, meninges, pituitary, cranial nerves, cerebral blood vessels and embryonic residual tissues, which are called primary intracranial tumors. Malignant tumors that have metastasized from other organs of the body to the intracranial are called secondary intracranial tumors. Intracranial tumors can occur at any age, with the most common being 20-50 years old.

[Traditional Chinese Medicine's Understanding of the Causes of Brain Tumors] Due to long-term diet structure, living habits, environment and other factors that cause acidification of the body, the overall immune function of the human body declines, causing

Brain tumors can be complicated by the following diseases:

Local symptoms are also known as localized symptoms.

The most common brain tumor is

(I) Symptoms of increased intracranial pressure occur in more than 90% of patients with brain tumors, and their manifestations are:

1. Headaches, nausea, vomiting, and headaches are mostly located in the forehead and temporal area. For persistent headaches, the paroxysmal aggravates, often in the morning. The headache is more severe, and the interval can be normal.

2. Nipple edema and vision loss.

3. Mental and conscious disorders and other symptoms: dizziness, diplopia, transient dark haze, sudden collapse, blurred consciousness, restlessness or indifference, epilepsy and even coma may occur.

4. Changes in vital signs: Moderate and severe acute intracranial pressure increases often cause breathing, pulse, slowing, and blood pressure.

(2) Local symptoms and signs: It mainly depends on where the tumor grows, so you can make a localized diagnosis of the tumor based on the patient's unique symptoms and signs.

Clinical symptoms of cerebral hemisphere tumors

1, mental symptoms: mostly manifested as slow response, lazy life, near memory loss, or even loss, loss of self-knowledge and judgment in severe cases, can also be manifested as irritability, irritability or euphoria.

2. Seizures: including generalized seizures and localized seizures. The frontal lobe is the most common, followed by the temporal lobe, parietal lobe, and the occipital lobe is the least common. In some cases, there are threats before convulsions, such as temporal lobe tumors and preeclampsia Premonitions such as fantasy and dizziness are often present, and abnormal sensations such as numbness of the limbs may occur before the onset of a parietal tumor.

3. Symptoms of pyramidal tract damage: the opposite side of the tumor or a single limb is weak or paralyzed with positive pathological signs.

4, sensory disturbance: manifested as the tumor's contralateral limb position perception, two-point discrimination perception, graphics perception, material perception, physical perception obstacles.

5. Aphasia: Divided into motor and sensory aphasia.

6. Visual field change: visual field defect and blindness.

Clinical manifestations of sphenoidal tumors

1. Visual disorders: The development of tumors on the saddle that oppresses the intersection of vision and causes visual loss and visual field defects, which are often the main reason for patients with sphenoidal tumors to come to the doctor. Fundus examination can find primary optic nerve atrophy.

2. Endocrine dysfunction: If hypogonadism is low, men show impotence and hyposexuality. Women manifest as prolonged or amenorrhea, excessive secretion of growth hormone before development and maturity can cause giant disease, and cyanotic atrophy after cyanosis.

Clinical symptoms of pineal tumors

Symptoms of compression of the quadruplex: concentrated in two aspects, namely: visual impairment, pupils' reaction to light and regulation, tinnitus, deafness; unstable holding, gait, eye level tremor, paralysis of limbs, both sides Pyramid bundle sign; diabetes insipidus, drowsiness, obesity, systemic developmental stasis, and precocious puberty in men.

Clinical symptoms of posterior cranial fossa tumors

1. Cerebellar hemisphere symptoms: mainly manifested as ataxia of the affected limb, weakened or untensioned muscles on the affected side, sluggish knee tendon reflexes, horizontal eye tremor, and sometimes vertical or rotational tremor.

2. Cerebellar vermiform symptom: Mainly manifested as ataxia of trunk and distal lower limbs, two feet separated too far while walking, staggered gait, or shaking like drunks.

3. Brainstem symptoms: The characteristic clinical manifestations are the occurrence of cross paralysis. If there are many midbrain lesions, it is manifested as oculomotor nerve palsy on the lesion side and pontine lesions. It can be manifested as eyeball abduction and facial muscle paralysis on the lesion side. Partial sensory disturbance and hearing impairment, medulla oblongata may appear ipsilateral tongue muscle paralysis, throat paralysis, and loss of taste in the third of the back of the tongue.

4. Cerebellar pontine angle symptoms: often manifested as tinnitus, hearing loss, dizziness, facial numbness, facial muscle twitching, facial muscle paralysis and hoarseness, fresh water cough, ataxia on the affected side, and horizontal nystagmus.

(3) Progressive course, no symptoms of compression may appear in the early stage of the tumor. With the growth of the tumor, the clinical symptoms often show different degrees of compression. Depending on the location of the tumor and the degree of malignancy, the rate of tumor growth varies, and the symptoms progress. There are also fast and slow.
