The third ventricle tumor Symptoms

The third ventricle as a result of lacunar small, early tumors easy access obstruction of cerebrospinal fluid circulation, resulting in increased intracranial pressure and gradually increase. If the tumor has yet to produce a smaller obstruction, the patient may have no obvious symptoms. When the third ventricle tumor surrounding tissue is generated when the focal symptoms.

Common The third ventricle tumor Symptoms include:

1. Intracranial hypertension: obstruction due to tumor obstacles so that the occurrence of cerebrospinal fluid circulation have increased intracranial pressure in patients with clinically manifested as severe headache, nausea and vomiting. The headache is often due to head position and position changes can be temporary relief, this may be due to the valve was shaped interior of the tumor in the brain occur so that temporary relief from obstruction, cerebrospinal fluid circulation path to be open so that to reduce or stop the headache. Re-obstruction, such as headaches, complex attacks, severe cases, coma or even death can occur. Patients often place the performance of forced and compulsory first position, the majority of patients in the supine position to increase when the headaches, alleviate prone. Therefore, in patients with sleep for more than the position taken in order to alleviate the headache attack.

2. Focal symptoms: When the tumor and nearby brain tissue invasion occurs when the focal symptoms. As a result of tumor location and direction of development which is different from its performance the same for the most common symptoms of hypothalamic damage. It includes the function of endocrine and metabolic disorders, such as changes in sexual function, obesity, malnutrition and reproductive incompetence metabolic syndrome, as well as barriers to water and salt, which is the third ventricle tumors often the main symptoms. Clinically manifested as loss of libido, impotence, irregular menstruation or menopause; in the incidence of children who may be precocious puberty. Because the hypothalamus and fat metabolism, it can be caused by abnormal fat distribution and the occurrence of obesity, diabetes insipidus and some patients, when the appetite center when violations anorexia, loss of appetite sometimes hyperthyroidism, the disease process in a small number of patients sleepiness . Back the development of tumors in the brain, the four stacked body damage on the patients, as the difficulties, hearing loss and oculomotor nerve palsy. The third ventricle tumors often affect the hippocampus - the hypothalamus - the hypothalamus and the link between the mamillary body, patients may have symptoms such as memory loss and mental changes. When the tumor suppression effects of the blood supply to the brain stem will occur when the strength of both lower extremities receded, the patient has cold feet. Anterior third ventricle tumor as a result of the optic nerve, optic chiasm caused by violations of vision loss and visual field defect. Between a small number of patients with cerebral seizures, clinically manifested as nausea and vomiting, sweating, face flushing, pupillary changes, autonomic symptoms such as palpitations.

3. Impaired vision: change the patient's retina is mainly caused by increased intracranial pressure papilledema, showing the boundary for nipple confusion, the disappearance of physical depression. Outdoor some from the third cerebral ventricle and the third invasion of the tumor growth, because of its oppression of the optic nerve directly, resulting in primary optic atrophy, such as craniopharyngioma, pituitary adenoma and so on. Long-term occurrence of intracranial hypertension secondary to optic atrophy, decreased vision or even blindness patients.

4. Other: Outdoor invasion from the third cerebral ventricle and the third of the tumor growth has its primary site of special clinical manifestation, such as the emergence of craniopharyngioma and pituitary adenoma pituitary dysfunction and visual field of vision disorders, as well as change. Pineal tumor patients with hypothalamus damage in addition to symptoms, but also appear stacked four special performance of physical damage, there Parinaud (Parinaud) syndrome. Patients pupil size or bilateral mydriasis; genital development levy and the second characteristics, sexual precocity; abnormal bone growth.
