Why does the spinal dura mater not have two layers like the cranial dura mater?

Why does the spinal dura mater not have two layers like the cranial dura mater?

Periosteum: The outer layer of the cranial dura mater derives from the periosteum of the inner table and it is not tightly attached to the skull. It can be dissected away from the skull and separated from the inner layer of the dura. In the spine, the periosteum attaches tightly to the vertebra and the epidural space is between that and the dura mater. ...Read more

Where does nucleus pulposus develops from?

Where does nucleus pulposus develops from?

Embryology: It originates from a flexible rod-shaped body called the notochord (part of an embryo). The notochord is found ventral to the neural tube. It is found in the center of each disc space and surrounded by the annulus fibrosis. When a disc herniates, the nucleus pulposus escapes from the center of the disc space, navigates through a rent in the surrounding annulus fibrosis, and can push on a nerve. ...Read more

Dura mater in brain and spinal chord, can you tell me more?

Dura mater: The dura mater is a thick membrane that covers the brain and the spinal cord, it is a protective membrane and holds the brain and spinal cord in place and is also the structure that gets infected when one has a "meningitis" ...Read more

Spinal MRI- multilevel disk & facet degen. scar tissue encasing S1,roots, Bulges &herniations, flat vent. dural sac, narrow foramin/spinal. Bad pain?

Spinal MRI- multilevel disk & facet degen. scar tissue encasing S1,roots, Bulges &herniations, flat vent. dural sac, narrow foramin/spinal.  Bad pain?

Degenerative disease: These findings may be the cause of your back pain. But how to take care of the pain is a whole other concern. You may do well with a combination of pain pills, muscle relaxants, physical therapy, and pain patches or liniments. Rheumatologists and orthopedists can give injections after doing tests to pinpoint the location and mechanism of the pain, such as pinched nerves. Lastly operation if need ...Read more

How herniated nucleus pulposus develops?

A disc herniation: The nucleus pulposus is the middle soft part of the disc in the spine that normally acts like a cushion. It looks and feels like a thick jelly material. Sometimes, it can leak out if there is a tear in the outside part of the disc (called the annulus fibrosus). When it leaks out, it can pinch a nerve and cause pain that radiates into the extremities. ...Read more

If a dura patch leaks post op posterrior fossa decompression, is surgical repair necessary?

Sometimes: Definitely needs to be watched carefully. Sometimes resolves with a spinal drain alone, but sustained leakage through the wound requires re operation. ...Read more

Interpret-please.mild broad-based disc bulge L5-S1 may contact S1 nerve root emerging from dural sac. 2 nerve roots don't appear compressed.

Interpret-please.mild broad-based disc bulge L5-S1 may contact S1 nerve root emerging from dural sac. 2 nerve roots don't appear compressed.

Back pain: It means the person who got this done was complaining of back pain probably with some radiation down one of the legs or perhaps even both. Symptoms of numbness, tingling, or burning pain may also be part of this picture. The MRI report is suggesting there is a bulging disc, which is not a hernia, which may be causing irritation of nerve fibers while not physically squeezing them. ...Read more

On cervical mri what does minimal CSF present within thecal sac mean? Narrowing anterior & posterior CSF spaces.

On cervical mri what does minimal CSF present within thecal sac mean? Narrowing anterior & posterior CSF spaces.

Space is tight: Sounds like this is concerning to you. It means that space is tight around the spinal cord. This usually isn't an emergency. You should discuss this finding with the doctor who ordered the test, who can put those findings into the context of your history and exam and can discuss next steps with you. Good luck! ...Read more

Mri report is right paracentral herniation of c5-c6 IV disc indenting spinal cord?

Any symptoms?: Some disc herniations may be asymptomatic. Would recommend a complete evaluation by a neurosurgeon. It is important to evaluate the amount of pressure on the spinal cord. ...Read more

My syrinx is almost wall to wall in my spinal cord. If they drain the syrinx will the spinal cord rejuvenate itself?

My syrinx is almost wall to wall in my spinal cord.  If they drain the syrinx will the spinal cord rejuvenate itself?

HARD TO PREDICT: If your syrinx is creating a compressive effect within spinal cord, risk of future deterioration is very real indeed, and would try to get this under control before more neurological disability ensues. Although you may not necessarily reverse all the pre-existing issues, the likelihood of prevention and cessation of the damage is very good if surgery is performed. Please discuss fully with doc. ...Read more

What is left parietal hematoma? 
Is parietal hematoma and subdural hematoma same?

Hematoma- blood coll: Hematoma is collection of blood somewhere in the body...anywhere in the body....it's called a hematoma. Parietal tells us the location (Parietal lobe of the brain) usually due to high blood pressure while Subdural hematoma means collection of blood below the level of the DURAL cover of the covering of the brain called the meninges...often times traumatic cause but also often can be spontaneous. ...Read more

What is left parietal hematoma? Is parietal hematoma and subdural hematoma same?

Different: A hematoma is like a bruise or collection of blood from a trauma. In parietal hematoma this is in the parietal lobe of the brain, so it is in the brain tissue itself. A subdural hematoma is just under the dura mater one of the coverings of the brain so it is up close to the skull. ...Read more

Neural prolotherapy l5s1 herniation with s car tissue around thecal sac abutting s1 nerve root..Pt, decompression , lyrica, (pregabalin) t3's.Could this help me?

Yes.: Neural prolotherapy, prolotherapy, trigger point injections, acupuncture, massage, myofascial release, rolfing and totally avoiding inflammatory foods may be more helpful than the medication. If there are tender knots in your upper butt muscles, most of your pain might be myofascial. www.blatmanhealthandwellness.com. ...Read more

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?

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 more
