Compare And Contrast Meninges Of Spinal Cord And Brain
Go to ER now: An infection of the area surrounding the brain can cause meningitis- fever, stiff neck, headache, and changes in conciousness. An infection within the brain itself is encephalitis- causing changes in personality, level of conciousness, and even seizures or other abnormal movements. These conditions are both very life-threatening, but treatable, and should be evaluated by a physician immediately. ...Read more
Prion: Prions are proteins that have changed conformation, so that the normal function of the protein inside the cells won't work. The prions' also causes other normal proteins to misfold and make more prions, spreading the process. The prions affect many cells in the body, but they particularly harm nerve cells in the brain, causing progressive rapid degeneration. They are not alive, and have no dna. ...Read more
Brain MRI is fine.MRI of whole spine showing supecious intramedullary hyperintensities in cord posterior to bodies of D6 to D8.
This is a: nonspecific abnormality that can be associated with a variety of demyelinating processes including MS. There are usually changes in the brain as well, but not always. Your doctor will interpret these findings in the context of your clinical/laboratory picture. ...Read more
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
Menigeal: Carcinomatosis (if a cancer) or lymphomtous or leukemic menigitis. The former carries a poor prognosis. It is addressed in children with cranio-spinal irradiation and intr-thecal chemotherapy. In adults with solid tumors, it is a mark of quite advanced disease, causes cranial neuropathy, and weakness. Rarely only site of disease. ...Read more
Mri showed multiple demyelinating lesions in cervical and upper dorsal cord and one in the brain. The rest of exams are negatives. Do i ve ms?
MRI results: It is possible that MS caused these demyelinating lesions. There are other causes too. Unless there are some other causes your doctor is considering, you may be prepared to think more about MS. MS can be treated effectively these days and it may not interfere with lifestyle. Once the diagnosis is clear, you may talk about some treatment options to prevent any more symptoms in the future. ...Read moreSee 1 more doctor answer
Maybe safer in some: Gadolinium contrast could potentially cause kidney complications on rare occasion. Mri without contrast will reveal areas of atrophy, stroke, bleeding, tumors, hydrocephalus, etc, but will not clearly show certain ms lesions, aneurysms, avm's, some inflammatory problems, so, always discuss with your doctor as to why an ordered MRI might be done in a variety of ways. ...Read moreSee 2 more doctor answers
Spinal Cord Tumor: Although spinal cord tumors are rarer than brain tumors, lesions of the spinal covering (meningiomas), spinal nerves (schwanomma or neurofibroma) or a metastatic tumor from breast or prostrate are the most common tumors to wrap around the spinal cord. Tumors of the spinal cord (ependymoma or astrocytoma) may look like its surrounding the cord, but are usually inside the tissue. ...Read moreSee 2 more doctor answers
Is it possible to crack the skull and preserve the brain at low temperatures? Without brain dying and the whole spinal cord.
Hmmmm..: Not sure how to answer. Many an unfortunate individual has actually cracked their head in the snow and been preserved for several hours with complete recovery. How long were you proposing to preserve things? There is no way to remove the brain from the body without detaching the spinal cord - this would be a major stumbling block to preserving anything of use.... ...Read more
Hmmm: Can't be described in 400 characters. Probably can't be appropriately described in a 400 page text book. There are 7 cervical vertebrae, 12 rib bearing thoracic vertebrae, 5 non-rib bearing lumbar vertebrae (there are normal variants to these by the way) .There are 5 fused sacral vertebrae, and usually 3 vestigial coccygeal bones. The spinal cord extends from the brain down to about l1/l2, and.... ...Read moreSee 1 more doctor answer
What areas of brain does "mri brain stem w/o dye" image or cover?Is mra included in above and does it like mra image or look for cerebral aneurysm?
Whole brain stem: The MRI would look at your entire brainstem, shown in the picture. The brainstem is the lower part of your brain that controls breathing and heartrate. An mra (magentic resonance angiogram) is not the same, and would be ordered as a separate test with dye injection. An mra looks at blood vessels for aneurysyms, obstructions, or tears, while an MRI looks for tumors, demyelination, or strokes. ...Read moreSee 1 more doctor answer
Look up the anatomy: Spinal cord is a neurological structure which runs inside the spine; the space inside the spine is called spinal canal. Cord is a vital organ that controlls our arms and legs movements, whereas the spinal canal is just a channel wherein lies the spinal cord. ...Read moreSee 1 more doctor answer

No cord compression. Vertebral bodies and spinal cord anormal.spinal canal adequate. A hemangioma in the T6 vertebral body is noted. What does this me?
Mostly benign: Vertebral hemangiomas are benign vascular malformations that displace the adjacent bone. They are usually asymptomatic and typically no treatment is necessary. Acute symptoms may occur from secondary compression fracture, sudden mass effect, and internal hemorrhage. With these secondary effects, there are invasive and noninvasive therapeutic options. ...Read moreSee 1 more doctor answer
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
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
