Meningioma tumor types
Meningiomas are tumors that arise from the meninges, the tissue layers that cover the brain and spinal cord... While most meningiomas are benign... but due to their location, they can cause important problems... Among the types of meningioma brain tumors, the following can be mentioned:
### Convex meningioma tumor
Convex meningiomas grow on the surface of the brain, usually in the outermost layer called the convexity..These tumors are easier to diagnose and treat..because they do not tend to invade the brain....however, depending on their size and location, they can put pressure on the brain leading to symptoms such as headaches, seizures, or weakness in certain parts of the body....surgical removal is often a good option for this tumors and has a relatively high success rate.
### Olfactory meningioma tumor
Olfactory groove meningioma develops near the front of the skull, around the olfactory nerve, which is responsible for the sense of smell. For this reason, early symptoms often include loss of smell. As the tumor grows, it can affect the frontal lobe of the brain, potentially causing personality changes, vision problems, or headaches. It is difficult.. but with modern surgical techniques, many patients recover well.
### Cerebral Meningioma Tumor CP Engel
Another type of meningioma brain tumor is angular meningiomas CP which grow in the space between the brainstem and the cerebellum.. an important area through which several cranial nerves pass.. these tumors can affect hearing, balance and facial sensation because They compress adjacent nerves... Symptoms may include vertigo, hearing loss, or facial numbness. Surgery in this area is challenging due to its complex anatomy.. But it is often the best treatment option.
Glioma tumors
Glioma is a type of tumor that starts in the brain or spine and is formed from glial cells that support and protect nerve cells.. Glioma is the worst type of brain tumor that has many types, but two of the most common ones are glioblastoma (GBM and we explained more.. Below:
### Glioblastoma (GBM)
Glioblastoma, often known as GBM, is the most dangerous type of glioma brain tumor. This tumor grows quickly and invades tissues around the brain, making it difficult to treat. lang="FA"> It affects the glial called astrocytes and is classified as a grade 4 tumor, which is the highest grade for any type of brain tumor.. meaning it is the worst type of brain tumor....
Symptoms can develop quickly and include headaches, memory problems, seizures, and changes in mood or behavior. Because GBM spreads quickly, surgery, radiation, and chemotherapy are often used together. They stay.
### Astrocytoma
Of the types of brain tumors that are usually malignant, we can mention astrocytomas that arise from astrocytes.. But their severity can be very different... They are graded from 1 to 4.. Grade 1 and 2 astrocytomas grow more slowly and are considered low-grade tumors.. Grade 3 astrocytomas, which are called anaplastic astrocytomas, grow faster and The worst type of brain tumor is this grade... Symptoms depend on where the tumor is in the brain... but can include headaches, nausea, and neurological changes such as muscle weakness or speech problems... Treatment options for astrocytoma depend on the grade of the tumor.. But it may include surgery, radiation therapy and chemotherapy.
Acoustic neuroma tumors
Acoustic neuroma, also known as vestibular schwannoma, is a non-cancerous brain tumor that develops on the vestibular nerve. It connects the inner ear to the brain and is responsible for hearing and balance. Acoustic neuromas are benign.
But they can still cause important problems during growth and put pressure on the surrounding structures.
Symptoms often begin subtly and may include hearing loss (especially in one ear), tinnitus (ringing in the ear), and balance problems. If the tumor affects nearby nerves, some people may experience numbness or weakness in the face.. although the exact cause is often not related to an acoustic nerve disorder.. Neurofibromatosis type 2 (NF2) are related.. Treatment options also vary depending on the size and speed of tumor growth.
Metastatic brain tumors
Metastatic brain tumors occur when cancer cells spread to the brain from another part of the body.. These are not types of brain tumors.. because they do not start in the brain, but are secondary growths from cancer elsewhere, such as the lungs, breasts, kidneys, or skin.. When cancer spreads to the brain, it can cause a variety of symptoms, depending on the size and location of the tumor.. Common symptoms include headaches, Seizures, balance problems, and cognitive issues such as memory loss or confusion are treated with radiation therapy... Advances in targeted therapy and immunotherapy also help some patients... However, metastatic brain tumors are usually more challenging to treat than primary brain tumors because they have already spread throughout the body.
Pineal tumors
Pineal tumors are one of the rarest types of brain tumors that occur in the pineal gland, a small pea-shaped gland located deep in the brain. This gland is responsible for producing melatonin, a hormone that regulates the sleep-wake cycle. There is pineal, including pineoblastoma, which is the worst type of brain tumor in this group and is often seen in children.. but it often includes headaches, vision problems and balance problems.. As the tumor grows, it can put pressure on the structures around the brain and lead to more severe complications.. Chemotherapy.
Pituitary tumors
Among other types of brain tumors, pituitary tumors are abnormal growths in the pituitary gland...a small gland at the base of the brain that regulates various body functions through hormone production....most pituitary tumors are benign and grow slowly....they can cause problems by pressing on surrounding structures or by producing excess hormones....
Symptoms of pituitary tumors vary depending on their size and the hormones that affect them. Some common symptoms include headaches, vision problems, and hormone imbalances that can lead to conditions like Cushing's disease or acromegaly.. Depending on the type of tumor and its effects on the body, treatment or often involves radiation, surgery, therapy... While these tumors are not usually life-threatening, If not managed properly, they can significantly affect the quality of life and turn into dangerous brain tumors.
Types of brain tumors and their treatment
There are different types of brain tumors that include primary and secondary tumors.. Primary tumors arise from brain tissues and include astrocytoma, meningioma and glioma and are usually the worst type of brain tumor.. Secondary tumors that are transferred to the brain from other parts of the body are also common.... Documents For effective treatment refer to **Skilled brain tumor surgeon** It is necessary.... Reputable surgeons like Dr. Yazdan Panahi in Tehran can provide accurate advice and appropriate treatment.
