Symptoms of brain space occupying lesions?

summary

Intracranial space occupying lesions are a group of diseases that occupy a certain space in the cranial cavity. Clinically, they are characterized by increased intracranial pressure (i.e., adult intracranial pressure > 200mmh2o) and focal nerve damage, among which intracranial tumors, intracranial hematomas and brain abscesses are common. Symptoms of brain space occupying lesions? Let's talk about it

Symptoms of brain space occupying lesions?

Mass like lesions occupying a certain space in the cranial cavity. Such as brain tumor, brain abscess and hematoma. With the increase of lesion volume, the physiological regulation of intracranial pressure is decompensated, and the intracranial pressure exceeds the normal value (80-180mmh2o), which is often accompanied by brain dysfunction.

When intracranial pressure increases, the meninges, important blood vessels and nerves are pulled. The onset of the disease is not typical at the beginning, and it may be persistent or even intolerable in severe cases. Brain stem displacement and traction or tumor directly stimulate the vomiting center of medulla oblongata, vomiting is jet, without other gastrointestinal symptoms, often occurs when the headache is severe, and the headache is slightly relieved after vomiting. Because the tumor often occurs in the posterior fossa in children, vomiting can occur in the early stage, and it is easy to be misdiagnosed as digestive tract disease.

Intracranial pressure was increased, ophthalmic venous reflux was blocked, optic papilla boundary was not clear, venous congestion, exudation or bleeding. The visual acuity was normal in the early stage and decreased gradually in the middle and late stage due to secondary optic atrophy.

matters needing attention

Asparagus is rich in anti-cancer element selenium, which can prevent cancer cell division and growth, inhibit the activity of carcinogens and accelerate detoxification, even reverse the cancer cells, stimulate the body's immune function, promote the formation of antibodies, and improve the resistance to cancer.
