Acoustic Neuroma Brain And Nerves
I have a brain tumor also trigeminal neuralgia . I'm planning on the brain surgrey tumor on the trigeminal neuralgia nerve. Can they remove the tnnerv?
Usually No: It sounds like you have a tumor (usually a meningioma or schwannoma) attached to the trigeminal nerve. This can cause the facial pain that you note. When surgery is done for this, the neurosurgeon can usually peel the tumor away from the nerve. Some fibers of the nerve can be sacrificed hopefully with minimal neurologic sequelae. This is a big nerve and it controls facial sensation and chewing. ...Read moreSee 1 more doctor answer
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Are sparkles in vision a sign of brain tumor? Why? Because of optic nerve or chiasm pressure?Or occipital/parietal lobe pressure? Please elaborate
Hemorrhage: Most of the damage of an arteriovenous malformation occurs when the blood vessel or vessels are spontaneously ruptured and bleed into the brain, causing pressure and damage to the brain. The same can occur with an av malformation in the brain stem or spine. ...Read moreSee 1 more doctor answer
Enlarged perivascular space in basal ganglia. Is by any cranial nerves? Double vision, enlarged pupils, trigeminal neuralgia, pulsating tinnitus
Are sparkles in vision a symptom of brain tumor? Why? Is it due to pressure in optic nerve or chiasm? Or occipital lobe or parietal lobe pressure.
No.: None of the structures you mentioned would cause sparkles in the vision. Scotomas are benign as long as they aren't persistent, they can be due to onset migraines, associated with headaches or happen for no reason. If they come on and stay and get worse for several days then we worry about retinal/vitreous detachment. ...Read more
Yes : If pituitary tumor is suspected a detailed endocrine evaluation is necessary to assess whether it is a functionally secreting tumor. Especially looking for acth secreting tumors given your history there are other types that present with generalized symptoms but a thorough endocrine evaluation should establish this in addition a very refined mri. ...Read moreSee 2 more doctor answers
Please interpret. Prominent aica branches extending in both auditory canals. Can be compressing 7th and 8th nerve complexes. Have vertigo and tinnitus?
AICA: A prominent aica is a variant of normal anatomy. The aica is the anterior inferior cerebellar artery. It can be found within the canal called the iac or internal auditory canal, which is where the facial nerve (7th) and the cochlear vestibular nerves (8th) extend from the ear to the brain. If the aica is prominent, it is large and can compress and result in tinnitus, vertigo & even hearing loss. ...Read more
Possibly: Magnetic resonance imaging, is a non-invasive, non-radiation method of cross section imaging. It is used to look at soft tissues, blood vessels and bone. Mri spine imaging will look at bone and the spinal cord with spinal nerves cords. An aneurysm is a blood vessel defect, usually of an artery such as the aorta, which lies in front of the spine. Whether this is seen depends on the image window. ...Read moreSee 1 more doctor answer
Not quite correct: For years, it was felt that nerve cells would not heal. If the cell body dies (apoptosis), it does not resurrect. If the nerve fibre axon is transected, it will not reconnect. But the myelin covering can regenerate, and the brain can employ alternative pathway connections with time. ...Read more
Quite possibly: Spinal cord stimulation (SCS) is used successfully in Neuropathic pain of peripheral nervous system origin. Neuropathic pain is a common healthcare problem with some patients who are refractory to standard treatment guidelines or burdened with the side effects of such treatments. SCS offers a clinical and cost-effective treatment at lower lifetime healthcare cost with better long-term outcomes. ...Read moreSee 4 more doctor answers
Can a dr (neurologist ) see and detect an inflammation of the optic nerve (optic neuritis) via a brain mr+c?
Visual field defects: As the tumor compresses the optic nerve, there will be a visual field defects. This can be in one eye if it happens before the optic chiasm or in both eyes if it happens after the chiasm. If there is any visual field defects, the tumor should be removed. ...Read moreSee 1 more doctor answer
No, but: The visual phenomena of migraines is caused by changes in blood flow as the arteries in the head narrow (spasm). Brain tumors can also cause visual changes, usually loss of peripheral vision, but other visual phenomena similar to migraines are known to occur. Brain tumors are rare; migraines are not. ...Read more
