What do swellings on the dorsal roots of the spinal nerves signify?

Nerve cell bodies: The dorsal root ganglion (the enlargement) is the place in the nerve where the cell bodies of feeling nerves (sensory nerves) are located. ...Read more

Nerve (Definition)

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

I have a swelling on the left side of my rib cage, at the same time I have frozen shoulder, was massage on the back spinal cord area. What causes it?

Rib cage swelling: There may be many different reasons why you have swelling around your rib cage. Possible causes include, but are not limited to: rib contusion, rib fracture, costochondritis, shingles, and intercostal neuritis. I would seek a formal evaluation from a qualified medical professional - especially if your swelling is associated with chest pain and/or associated skin lesions. ...Read more

Can a cranial spinal fluid leak be caused by a papilledema or swelling of the optic nerve?

Can a cranial spinal fluid leak be caused by a papilledema or swelling of the optic nerve?

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

Can you tell me the function of the dorsal root of the spinal nerve?

Can you tell me the function of the dorsal root of the spinal nerve?

Lets you feel things: The nerve root has 2 "ganglions". The dorsal root is on the posterior side of the nerve (closer to your back) and carries the fibers that allow you to feel things in your extremities (for example: pain, temperature, vibration). The information is transmitted to your brain so you understand what type of sensation is being encountered by the extremity. ...Read more

What will happen if an injury cuts the dorsal root of a spinal nerve that carries feelings of pain?

What will happen if an injury cuts the dorsal root of a spinal nerve that carries feelings of pain?

Numbness: The dorsal (posterior, toward the back) root carries sensation nerve fibers: feeling of light touch, vibration, sense of position (movement or where the arm or leg or joint is), pain. However, there is much overlap between the area serves by a single nerve, so there may not be total loss of sensation, depending on how the person is "wired.". ...Read more

A homework question?: You're 34 so I'm guessing it's not a homework question. I just did a web search using your question & got a great profusion of hits. Don't take offense, but HealthTap docs do this to apply medical reasoning to posters' questions, not so they can regurgitate facts that anyone, physician or nonphysician, can look up for themselves. ...Read more

What are the sign & symptoms of spinal swelling?

What are the sign & symptoms of spinal swelling?

Depends: It depends in part on the part of the spine involved. When nerve roots are involved, it usually involves pain, numbness, or weakness along the distribution of the nerve in the arm or leg. If it is the spinal cord itself, then swelling can lead to numbness, weakness, clumsiness, loss of bowel and bladder control, and even paralysis and/or respiratory arrest. ...Read more

Please describe the medical term of spinal swelling?

Please describe the medical term of spinal swelling?

Edema: Edema is the term that is used when referring to spinal cord swelling. This can occur, for example, after an injury. At the cellular level, this means that the cell membranes become 'leaky' and some of the intracellular fluid spills out. This leads to additional pressure on the surrounding nerves. There are two main types-cytotoxic and vasogenic edema. This depends on the cause of injury. ...Read more

After septorhinoplasty, (Im almost 4 weeks post op) how do you know if a residual dorsal hump is swelling or otherwise? Does the Dr. Really even know

Post op rhinoplasty: It is possible that there is some swelling accounting for the appearance of your nose. Post op changes in rhinoplasty can take many months to resolve. If however, there is a very obvious residual hump, it may not go away completely. It is hard to have patience when you are looking at your nose every day, Give it some time and continue to check in with your surgeon. ...Read more

The MRI says "severe" disc herniation and spinal cord swelling and compression" what does this mean?

The MRI says "severe" disc herniation and spinal cord swelling and compression" what does this mean?

Not good: Your veretebrae bones are seperated by the discs. Your vertebrae make a canal that your spinal cord is protected by. If your disc has a severe herniation, then the contents of the disc are now pushing up against the spinal cord within the spinal canal. Think of your disc as a tube of toothpaste that was left open and now toothpaste is coming out. See your doctor, this needs to be addressed. ...Read more

Mri reading need interpretation, focal swelling with heterogenous abnormal signal in the spinal coed atc5-c6 level suggesting neoplasm has improved?

Need to discuss with: As stated, this sounds as if you had a type of previous "neoplasm" and the test is showing an improvement in the swelling around certain areas of your neck at c5-6. Possibly the radiologist did not know your history of previous neck surgery in the area. I recommend you have the ordering dr discuss your hx and the findings with the radiologist and then discuss in detail with you. Best wishes. ...Read more

WatchOutForTheNoNose: This is a difficult question to answer;depends on the cause of the swelling.15 weeks after surgery raises certain questions that your plastic surgeon should be able to answer. Generally, if it's felt there's residual inflammation, it might work to some degree. But if due to micro scarring or some other anatomic cause, probably not. Also what about you? Sleeping flat? Yoga? Boxing? Etc. These are no-no's! ...Read more

How is x ray Abn.?: An "abnormal" x ray could be anything from just reporting the swelling which is already known to a bone, joint or soft tissue problem which may or may not be related to the dorsal swelling. All plain x ray findings are not necessarily serious.
Advice about what to do should be only offered after clinical exam and more history. Sorry. ...Read more

Would a cat scan show the inflammation or swelling from primary amoebic meningoencephalitis? If there was signs would there then be a spinal tap?

Maybe.: Ct is not the best test for early infectious processes in the brain. Mri with contrast is best, but much longer and not always available. If amebic encephalitis is suspected, a lumbar puncture (spinal tap) would be appropriate, even if the ct is normal. ...Read more

Need advice on MRI results. Abnormal heterogeneious t2 signal with some swelling within the spinal cord at c5-c6 level, husband had fusion 1.5 years ago on on c4-c6 is this getting worse?

Need advice on MRI results. Abnormal heterogeneious t2 signal with some swelling within the spinal cord at c5-c6 level, husband had fusion 1.5 years ago on on c4-c6 is this getting worse?

Communicate: This is a situation in which the MRI findings must be correlated with both the clinical presentation and the prior appearance of the images. This should be discussed at length with the physician who ordered the test, and information on the internet without actually seeing the images and your husband are unlikely to be helpful. Hope he does well. ...Read more

Recent MRI, please explain readings. Husband had fusion 2012 c4-c5. New MRI focal swelling with heterogeneous abnormal signal in the spinal cord atc5-c6 suggesting neoplasm has improved.

Funny MRI: Probably means something abnormal was seen at that level early and looks better. Not every neoplasm appearance is a tumor and not every tumor is a cancer so to really tell you need the ortho or neurosurgeon to compare results carefully with the radiologists help and answer your question better. ...Read more

Can a whiplash injury cause bone edema? I am being sent for an MRI following spinal x-ray, and am a little concerned. Whiplash injury 2 months ago, X-ray showed swelling and damage as well as bone oedema?

Can a whiplash injury cause bone edema? I am being sent for an MRI following spinal x-ray, and am a little concerned. Whiplash injury 2 months ago, X-ray showed swelling and damage as well as bone oedema?

The: The cervical spine is made up of spinal vertebrae, disks, joints, muscles and ligaments. Spinal injury may damage these structures and cause swelling, tearing and breaking of these structures. This can be seen as edema (swelling) in bones. Edema is best seen on mri. Whiplash usually injures the soft tissues (muscles, ligaments, etc). Severe whiplash injuries may injure the bones and cause bone edema. ...Read more

Recent MRI of cervical spine shows spinal cord swelling at c5- C6, had acdf sugery in sept. Why is there still swellinh?

Hard to say: There are multiple potential causes. It still might be residual from what you had before surgery, there may be continued compression, or have been a surgical complication. Your surgeon would be the best to interpret the meaning of the study based upon your individual case. Thank you for your question. ...Read more
