Frontal lobe tumor operation effect how?
summary
Frontal lobe tumor is a common intracranial tumor, so the patient's diet should be reasonable. Do not overeat, the incidence of supratentorial tumors ranked first, accounting for about 1 / 5 of the total number of intracranial tumors. Gliomas are the most common, accounting for about 1 / 4 of the total number of intracranial gliomas; Meningiomas accounted for 1 / 10 of the total intracranial meningiomas; In addition, congenital tumors and metastases often occur in this area. What's the effect of frontal lobe tumor surgery? Let's go.
Frontal lobe tumor operation effect how?
First, frontal lobe subdural hematoma is a common clinical disease, which can be seen at any age. Most of them have obvious history of trauma. They have symptoms of increased intracranial pressure soon or several months after injury. The limited signs are not obvious, but the mental symptoms are obvious. A few patients may have seizures, especially chronic or subacute subdural hematoma. It is difficult to differentiate from tumors according to clinical manifestations, The diagnosis of frontal subdural hematoma can be made by angiography and CT examination. In the anteroposterior images, the anterior cerebral artery moves in an arc to the opposite side, the middle cerebral artery presses down and moves to the medial side in varying degrees, and there is often a half moon shaped avascular area between the blood vessels and the inner plate of the skull. CT is very useful for the location of hematoma.
Second, the clinical symptoms and signs of frontal lobe abscess and tumor are basically the same, but the brain abscess is mostly secondary to the infection focus of other parts of the body, with acute onset, a history of fever, increased peripheral blood picture and polymorphonuclear leukocytes in cerebrospinal fluid, and about 50% of brain abscesses in the microvascular venous phase of carotid angiography can show a uniform opaque area on the wall, It can be regarded as the characteristic change of brain abscess. CT examination of brain abscess shows low-density area with clear edge, while tumor is generally high-density area, which is easy to distinguish. However, there are a few brain abscesses which are difficult to distinguish from tumor before operation, and can be diagnosed only after surgical exploration.
Third, craniopharyngioma is more common in school-age children and young people before 20 years old, rarely in adults, while frontal lobe tumors are more common in adults. The first symptoms of craniopharyngioma are endocrine dysfunction, growth retardation is common in children, and sexual dysfunction is common in adults. Frontal lobe tumors do not have the above symptoms, and their early symptoms are mostly mental disorders, But the mental symptoms of craniopharyngioma patients are rare and mild. Frontal lobe tumors often cause papilledema, and there is no visual impairment in the early stage. When the optic nerve secondary atrophy occurs in the late stage, there is visual impairment. Craniopharyngioma patients often see primary optic nerve atrophy, and there is visual impairment in the early stage, Craniopharyngiomas often have eggshell like calcification in suprasellar or intrasellar areas, accompanied by changes in shape and bone of sella turcica, while frontal lobe tumors rarely have calcification. In a few tumors with calcification, the location and shape of calcification spots are not as typical as craniopharyngiomas.
matters needing attention
Primary prevention refers to the promotion of health and the reduction of risk factors. The first line of defense is to promote the healthy lifestyle of the general population and reduce the exposure to harmful factors in the environment, so as to completely avoid the occurrence of cancer. As far as we know, besides preventing carcinogens and suspected carcinogens in the air, drinking water, food and workplace, we should also change the smoking in the lifestyle, Drinking and other bad habits are the contents of primary prevention.
