Meningioma (meningiota)

Meningioma

Meningioma is a tumor formed from the connective tissue of the meninges of the brain and spinal cord. The growth of these tumors is usually slow, but their development can cause a person to develop symptoms indicating compression of the brain structures located under the meninges. A tumor developing in the brain can cause focal epilepsy and gradually progressive neurological disorders in a person. A tumor of the spinal cord causes the development of paraplegia and Brown-Séquard syndrome in humans.

Some meningiomas (called meningeal sarcomas) are cancerous and can invade adjacent tissue. Most often, if possible, surgical removal of the meningioma is performed. Malignant tumors may also require additional radiation therapy.

There are cases where patients experienced the above symptoms for quite a long time, sometimes up to 30 years, before this tumor was detected.

Meningioma: Overview and Characteristics

Meningioma, also known as meningiota, is a tumor that develops from the connective tissue of the meninges of the brain and spinal cord. Although the growth of these tumors is usually slow, their development can cause symptoms indicating compression of the brain structures located under the meninges.

When meningioma develops in the brain, it can cause focal epilepsy and gradually progressive neurological disorders. A tumor developing in the spinal cord can cause paraplegia and Brown-Séquard syndrome. Some meningiomas, known as meningeal sarcomas or malignant type meningiomas, can invade adjacent tissue and be aggressive.

In most cases, if possible, the meningioma is removed surgically. Malignant tumors may also require additional radiation therapy. Often, symptoms of meningioma can occur for a long time, sometimes up to 30 years, before the tumor is detected.

However, it is important to note that meningioma should not be confused with meningitis. Meningitis is an inflammation of the lining of the brain caused by a viral or bacterial infection. Symptoms of meningitis include severe headache, fever, loss of appetite, intolerance to light and sound, muscle stiffness, especially in the neck, and in severe cases may include seizures, vomiting and delirium. Bacterial meningitis, especially in young children, can be caused by bacteria such as Haemophilus influenzae and Neisseria meningitidis. There is a possibility of vaccination against meningitis caused by these bacteria.

Bacterial meningitis is usually treated with high doses of antibiotics, and the sooner treatment is started, the better the patient's prognosis. Viral meningitis, with the exception of simple herpetic encephalitis, which can be treated with acyclovir, does not respond to drug therapy.

In conclusion, meningioma (meningiota) is a tumor formed from the connective tissue of the meninges. Although it can cause symptoms related to pressure on brain structures, in most cases Meningioma: Overview and Characteristics

Meningioma, also known as meningiota, is a tumor that develops from the connective tissue of the meninges of the brain and spinal cord. Although the growth of these tumors is usually slow, their development can cause symptoms indicating compression of the brain structures located under the meninges.

Meningiomas often grow slowly and are benign tumors. However, in some cases they can be malignant and invade surrounding tissue. Malignant meningiomas are less common and require more aggressive treatment.

A meningioma that develops in the brain can cause a variety of symptoms, including headaches, seizures, changes in vision and hearing, and various neurological disorders. Symptoms depend on the location of the tumor and the degree of compression of surrounding tissues.

A spinal cord tumor can cause compression of the spinal cord and nerve roots, leading to symptoms such as paralysis, sensory loss, and bladder and bowel dysfunction.

Various imaging modalities are used to diagnose meningioma, including magnetic resonance imaging (MRI) and computed tomography (CT). A biopsy may be performed to confirm the diagnosis and determine the nature of the tumor.

Treatment for meningioma usually involves surgical removal of the tumor. In most cases, complete removal of the tumor is possible, especially for benign tumors. However, malignant meningiomas may require combination treatment, including surgical removal, radiation therapy and chemotherapy.

The prognosis depends on the type and stage of the tumor, as well as its location and size. Benign meningiomas that are completely removed have a good prognosis and recurrence is rare. However, malignant meningiomas have a poorer prognosis and require more aggressive treatment.

In conclusion, meningioma (meningiota) is a tumor that develops from the connective tissue of the meninges. It can cause a variety of symptoms, and treatment includes surgical removal of the tumor and, if necessary, additional treatments. Early diagnosis

Meningiomas are benign non-epithelial tumors that develop from elements of the connective tissue sections of the walls of the brain capsule or spinal membrane. These tumors are almost never multiple. An exception is xanthomatosis of the brain in adults, which leads to the formation of many meningiomas. Otherwise, they are asymptomatic and are an incidental finding. The simplest method for detecting these tumors at the age of 20-55 years is magnetic resonance imaging of the brain, since the size of the tumor, even with high magnification, does not exceed 5 mm. Sometimes meningioma is discovered during surgery for another brain disease. Tumor changes do not cause diffuse changes in the brain substance. The boundary between them and the rest of the brain mass is clearly visible on CT - this is the pseudocystic component. However, on a CT scan, very small meningiomas are visible in the form of a nodule or change in density without disturbing the normal structure of the brain (except for the part into which the tumor directly grows). The radius of spread of extracerebrally growing meningioma rarely exceeds 1 cm. Intradural and intracranial growing meningiomas measuring several centimeters in size are much less common. Detection of such tumors is possible with the development of occlusion of the subarachnoid space or small perforating openings of the skull. The size of the tumor directly affects the amount of time that surgery may require. Sometimes patients can go up to 15-20 years or more before they are discovered. Considering these facts and the peculiarities of the course of the tumor process, we can state that symptoms occur in every 5-6th patient, and this tumor is found in every 18-
