What is bilateral thalamic glioma?
What is bilateral thalamic glioma?
Bilateral thalamic glioma are rare tumors of brain. Though they are benign in nature but their outcome is poor in comparison to unilateral thalamic glioma. They grow slowly and present with huge size involving nuclei of thalamus.
Is thalamic glioma curable?
If the MRI scan indicates the tumor is a focal (clearly defined) JPA of the thalamus, surgical removal of the tumor provides a realistic chance for a cure. Unfortunately, for most astrocytomas of the thalamus (infiltrative or diffuse Grade II-IV tumors), surgical removal is not an option.
How do you get glioma?
Risk factors include:
- Your age. Your risk of a brain tumor increases as you age.
- Exposure to radiation. People who have been exposed to a type of radiation called ionizing radiation have an increased risk of brain tumor.
- Family history of glioma. It’s rare for glioma to run in families.
What system is the thalamus part of?
limbic system
The thalamus is part of the limbic system, the region of the brain largely associated with the emotions and is essential to memory and learning. The thalamus joins a series of other machinery whose purpose is to distill sensory information into a more interpretable and manageable form for higher brain sections.
What part of the brain is the thalamus in?
diencephalon
The thalamus is a paired gray matter structure of the diencephalon located near the center of the brain. It is above the midbrain or mesencephalon, allowing for nerve fiber connections to the cerebral cortex in all directions — each thalamus connects to the other via the interthalamic adhesion.
How do you heal the thalamus?
The following are some treatments that can help you overcome the effects of damage to the thalamus:
- Physical Therapy.
- Sensory Reeducation Exercises.
- Speech and Cognitive Therapy.
- Deep Brain Stimulation.
Can glioma be removed?
Surgery. Surgery to remove as much of the tumor as possible is usually the first step in treating most types of gliomas. In some cases, gliomas are small and easy to separate from surrounding healthy brain tissue, which makes complete surgical removal possible.
Is glioma a death sentence?
Despite its reputation, a glioblastoma diagnosis is not necessarily a death sentence, thanks to significant medical advancements in recent years.
Why is the thalamus so important?
While the thalamus is classically known for its roles as a sensory relay in visual, auditory, somatosensory, and gustatory systems, it also has significant roles in motor activity, emotion, memory, arousal, and other sensorimotor association functions.
What disorders are associated with the thalamus?
Disorders of the centrally located thalamus, which integrates a wide range of cortical and subcortical information. Manifestations include sensory loss, MOVEMENT DISORDERS; ATAXIA, pain syndromes, visual disorders, a variety of neuropsychological conditions, and COMA.
What is the differential diagnosis of bilateral thalamic lesions?
Bilateral thalamic lesions are un- common. These paired lesions have a limited differential diag- nosis that includes metabolic and toxic processes, infection, vascular lesions, and neoplasia. The differential diagnosis can
Is the globus pallidus involved in bilateral thalamic lesions?
Extensive bilateral calcification of the deep gray matter is present and most frequently involves the globus pallidus (Fig. 5A, 5B, 5C ). Other areas of involvement include the putamen, caudate nuclei, thalami, and dentate nuclei [ 11 ]. Calcium–phosphorus metabolism is normal in these patients [ 11 ].
How can we improve the prognosis for thalamic gliomas?
The only way to improve the prognosis for thalamic gliomas and other rare and inoperable brain tumors in children is to study them, get to understand them better, and test innovative therapies for them.
How are abnormalities of the basal ganglia and thalamus diagnosed?
Radiologic Assessment of Abnormalities of the Basal Ganglia and Thalamus. In some of these situations, the radiologist may detect an unsuspected but readily apparent abnormality at CT or MR imaging, and the characteristic pattern at neuroimaging may be the first indicator of the correct diagnosis ( 14 ).
