MRI of my Cervical Spine There is disc degenerative changes with associated impingement of the thecal sac , exit neuroforaminal encroachment.



MRI of my Cervical Spine 
There is disc degenerative changes with associated impingement of the thecal sac , exit neuroforaminal encroachment.

MRI result?: So- what does this mean? It is common for MRI of the c-spine to show degenerative changes. Impingement of the thecal sac is not normally concerning. It is unclear what is meant by "exit neuroforaminal encroachment". Was there encroachment or not? If it is there, this normally means nerve root encroachment, which can cause symptoms that affect the arms. ...Read more

I have 2 herniated disks and 5 buldges one of the hern's l2/3 is deforming the thecal sac, the report says lumbar spine straightening. What can I do?

I have 2 herniated disks and 5 buldges one of the hern's l2/3 is deforming the thecal sac, the report says lumbar spine straightening. What can I do?

Sciatica: Pain in the distribution as you suggested describes the pattern of the nerve that travels in the leg called the sciatic nerve. The sciatic nerve is not the cause of the pain source, it is the result of an irritated nerve typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease requiring further evaluation by a spine specialist. ...Read more

About 20% of people: With lumbar spinal stenosis will have coexisting cervical spinal stenosis. Spinal stenosis is a narrowing of a bony canal structure such as the central spine canal or the exiting nerve holes known as neuroforamen which when severe enough by imaging studies will be deemed spinal stenosis. ...Read more

If .7 CM enhancing lesion in thecal sac near L4 is discovered on pelvic mri, would you have lumbar spine MRI first and then go to mayo, or would you wait and have lumbar spine MRI at mayo?

If .7 CM enhancing lesion in thecal sac near L4 is discovered on pelvic mri, would you have lumbar spine MRI first and then go to mayo, or would you wait and have lumbar spine MRI at mayo?

Ask them: Whether you go to mayo or another referral center (such problems are usually treated by neurosurgeons), each have there own preferences. Some like to review the study first, even before seeing you (so you could have the lumbar mri, with and without contrast in your community). Others like the study done at their site so they can specify the MRI sequences they desire. ...Read more

MRI report says - 1. Straightened lumbar spine curvature 2. posterior central disc protrusion at L4 -L5 level causing indentation of thecal sac ?

MRI report says -  1. Straightened lumbar spine curvature 2. posterior central disc protrusion at L4 -L5 level  causing indentation of thecal sac

?

Herniation and spasm: One way to describe those findings is you have a herniated disc likely associated with spasm. When paraspinal muscles go into spasm, the lumbar spine straightens out somewhat losing its normal contour. I would not hesitate to be seen to discuss treaent options. ...Read more

MRI cervical spine showed 2 central disc herniations, a bulge, 2 uncovertebral joint hypertophy into thecal sac. How long until i heal, i am doing PT.

MRI cervical spine showed 2 central disc herniations, a bulge, 2 uncovertebral joint hypertophy into thecal sac. How long until i heal, i am doing PT.

Can take 1- 2 years: MRI's of the cervical spine show the current state of the the spinal elements as they change over time.Several of those changes such as uncovertebral joint hypertrophy are a response to gravity and changes in the disc.The disc herniations will do their best to heal slowly over time, however they are due to aging and degeneration with water loss.In the meantime continue PT and regular f/u w/your MD ...Read more

I got my lumbar spine MRI which says, L4-5, Disk bulge is noted impinging on the anterior thecal sac near the exiting nerve roots. There is mild face?

I got my lumbar spine MRI which says, L4-5, Disk bulge is noted impinging on the anterior thecal sac near the exiting nerve roots.  There is mild face?

Mild Facet joint : I think you meant to type (Facet Joint ) not Face. Lumbar MRI evaluate the facet joints and can show degenerative changes ( fluid in joint, or hyper trophy which is enlargement ) and these changes can narrow the spinal canal and / or neural foramen narrowing ( where nerve exit the spine. ...Read more

What is the ventral thecal sac in the lower back?

What is the ventral thecal sac in the lower back?

Within the bony ---: Structures of the back, the spinal cord (sc), which is the continuation of the brain, lies. The sc is surrounded by a layer, called the thecal sac. The front aspect of this is called the ventral t sac, while at the back, its the dorsal (or posterior) t sac. Its present from the neck down to the lower back. This sac contains the spinal fluid which bathes the sc, providing it nutrition. ...Read more

I had a myelogram done and it showed two areas with a thecal sac deformity. Can this be dangerous? I had l3-4 surgery in the area noted back in 03.

I had a myelogram done and it showed two areas with a thecal sac deformity. Can this be dangerous? I had l3-4 surgery in the area noted back in 03.

Thecal sac deformity: It is common to find thecal sac deformities usually bulging discs. The most important thing is not the radiologic finding, but the clinical one: is there weakness or a loss of sensation or pain some place. If that place is the appropriate root, then maybe the deformity has clinical relevance. Classically, clinical signs and radiologic finding and electrodiagnostic abnormalitities must match. ...Read more

I had an MRI - says L4-L5- Disc buldge with superimposed central disc protusion. Severe spinal canal stenosis with compression of the thecal sac with bilateral neurofarminal narrowing. A chair broke and I collapsed on back. ?

Pinched nerve: Spinal stenosis is one way to say you have a narrowing or "pinching" of your nerve canal, in your case it is severe. The cause of the pinching is at least in part from a disc protruding into the nerve canal (herniated disc) which could potentially have occurred in the injury on the chair. I would not hesitate to be seen, many good treatment options available. ...Read more

Hi I have severe back pain daily. MRI and CT shows limbus lesion, L5 endplate collapse , interverteral disk mildly retropulsed and abutting thecal sac. Please help me understand this. Thankyou?

Hi I have  severe back pain daily. MRI and CT shows limbus lesion, L5 endplate collapse , interverteral disk mildly retropulsed and abutting thecal sac. Please help me understand this. Thankyou?

Several problems: Sounds like the spine is suffering degeneration. End plate is the we bearing surface of the lower vertebra, and it was flat, but now curved or irregular. Thus squeezed the disc, which has bulged out from its position and part of it is pressing against the sack that covers the spinal,cord, a potential pain issue. I have no clue what a limbus lesion is ...Read more

Broad based r. Paracentral disc protrusion, obliteration of thecal sac. Numb/tingle arm/hand, tinglin/dizzy from back of head to forehead, pain, bad?

Broad based r. Paracentral disc protrusion, obliteration of thecal sac. Numb/tingle arm/hand, tinglin/dizzy from back of head to forehead, pain, bad?

Paracentral disc protrusion: Obviously you saw a specialist, your condition requires removal of the protrusion, as is beginning to compress the spine. And the greater occipital nerves. I noted your medications. Please take it seriously, see a orthopedic surgeon, get his opinion. Now days surgery is minimally invasive, and the results are good. Make an appointment today. ...Read more
