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 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?

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

If you have a 1cm lesion in thecal sac of lumbar area with urinary ret and bowel dysmotility that improves with large doses (1200mg) of ibuprofen, could ibuprofen be reducing inflammation in spine?

Yes but: It is not a solution 4 the long term . C a spine surgeon, these r significant symptoms. If due 2 a disk, surgery. If due 2 a growth, removal & get a firm DX as 2 malignant or benign. ...Read more

As to nerve sheath tumors in thecal sac at l-4, in your experience do they typically grow or do they usually remain stable in size?

As to nerve sheath tumors in thecal sac at l-4, in your experience do they typically grow or do they usually remain stable in size?

Different speed: All tumors will grow, benign rumors grow very slowly and malignant tutors grow much quicker. Nerve sheath rumors are usually benign. Best to discuss this with your doctor. ...Read more
