Brain Tumour Causing Sudden Compression Of Optic Nerve
Are sparkles in vision a sign of brain tumor? Why? Because of optic nerve or chiasm pressure?Or occipital/parietal lobe pressure? Please elaborate
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
Can optic nerve head drusen cause sudden unilateral loss of peripheral vision due to a spontaneous vascular event?
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
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
Brain tumor: Tumors in the back part of the brain or posterior fossa can put downward pressure on the spinal cord and irritate the nerves in the neck. Muscle spasm can occur if there is erosion of the skull base and the occipital condyles. Blockage of cerebrospinal fluid as it flows from the brain to the spinal cord will cause neck pain. ...Read more
Mri showed branch of artery prolapsing into left ear canal w/ minimal compression of 7th&8th cranial nerves. what kind of symptoms could this cause?
Can degeneration of the C5-C6 vertebra cause episodic syncope due to vagus nerve damage or entrapment?
No but VBI might: VertebroBasilar Insufficiency (VBI) - The vertebral arteries run up the back of the neck thru tunnels (foramen) in the vertebrae (bones of spine). Some neck maneuvers can compress the artery where it passes thru the foramen. While not usually syncope, this can cause vertigo & drop attacks via buckling of the knees usually in older folks with degenerative spinal problems. aka beauty parlor syndrome. ...Read moreSee 5 more doctor answers
Can a small benign brain tumor on cerebellum cause nerves to be inflamed without causing raised intracranial pressure?
Different items: Papilledema is a sign of increased intracranial pressure of any etiology, and can be due to tumor, hydrocephalus, brain hemorrhage, infections. Swelling of the optic nerve can be due to optic neuritis or other inflammatory problems. Spinal fluid leaks can be due to trauma over skull such as cribiform plate fracture. If severe trauma, perhaps all could occur together. ...Read more
Probably not : The exact cause of multiple sclerosis is not well understood. However, researchers have looked at a link between brain injury and ms. It is a very weak relationship. About 1 person in 5000 who has a brain injury may get ms, so i wouldn't worry too much about it. ...Read moreSee 1 more doctor answer
Can sudden peripheral vision loss due to optic nerve head drusen reverse, change in severity or fully recover?
Not typical!: Optic nerve he'd drusens are associated with field loss sometimes, but they are chronic and stable. I am not aware of them being associated with sudden loss. Look for a different cause! depending on the that, it may or may not be reversible (most likely not). ...Read more
Similar: Brain tumors can cause an increase in intracranial pressure but there are other things that can cause this. Increased intracranial pressure is just the pressure inside of the skull. This pressure can be increased by tumors but also by injury, bleeding, swelling and fluid blockages. ...Read moreSee 1 more doctor answer
Usually: The symptoms are caused by tumor growing and pressing on the optic nerve and nearby structures. Symptoms may include: •involuntary eyeball movement, eyes bulging outward, squinting, loss of vision in one or both eyes leading to eventual blindness this may be losso of peripheral vision or more general loss. ...Read moreSee 1 more doctor answer
Can facial nerve palsy affecting the left lips, left eye blinking, and vocal cord all arising from trauma of gunshot at the neck, ear , be corrected?
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
