A nerve root impingement is what occurs when the root of a nerve i.e. the portion that enters the vertebral column via a vertebral foramen (hole in the spine) is pressed upon (impinged) by a number of possible things.
The more common of these being osteophytes (degenerative bony changes in the spinal body). A space occupying lesion (tumor of some kind begning or malignant). Spinal muscle tissue becoming hypertonic (stuck in contraction) and causing a narrowing of the foraminal space as a result. Disc degeneration resulting in a narrowing of the foraminal space. Trauma can also result in nerve root compression. Degenerative vertebral disorders (such as spinal TB, ankylosing spondylitis etc) may also result in nerve root compression.
Localised to the Cervical spine (neck) Thoracic outlet syndrome (can create nerve root impingement often resulting in parasthesia (abnormal sensation) and/or numbness in the arm and hand of the affect side (i.e left nerve root compression = left arm and hand issues). TOS is essentially the same as hypertonic changes in the muscles lower down however as it is such a common dysfunction it has its own name.
Nerve root impingement can create neurological symptoms (pain, parasthesia, numbness or in motor nerves, loss of motor function). These symptoms tend to occur below the site of impingement however they can also present above the impingement i.e pain in your neck as a result of a T1 impingement.

What is mild to moderate encroachment of exiting nerve root L4-L5?
Mild to moderate encroachment of the exiting nerve root at the L4-L5 level refers to a condition where there is slight to moderate compression or irritation of the nerve root that exits the spinal column at the lumbar spine's L4-L5 intervertebral foramen. This encroachment can result from factors such as bulging discs, bone spurs, or inflammation, potentially leading to symptoms like pain, numbness, or weakness in the lower back and legs. While it may not always cause significant issues, monitoring and management may be necessary to prevent further complications.
What is Nerve root clumping at L4 L5 and L5 S1?
Nerve root clumping is usually indicative of arachnoiditis, a painful, progressive spinal condition. Please research arachnoiditis.
What is perineural fat around the existing L5 root?
You probably mean exiting L5 spinal nerve--the nerve root ends at the DRG inside the lateral foramen. It is fatty tissue within the neuroforamen. Outside the foramen there is typically muscle.
What does an MRI mean when it says prominent left anterolateral disc protrusion extrusion at L5-s1 with recess and foraminal encroachment Nerve root effacement and displacement?
An MRI report indicating a "prominent left anterolateral disc protrusion extrusion at L5-S1" means that the intervertebral disc between the fifth lumbar vertebra and the first sacral vertebra is bulging and has partially ruptured. This protrusion is causing encroachment on the neural recess and foraminal space, potentially affecting nearby nerve roots. "Nerve root effacement and displacement" suggests that the protrusion is compressing and displacing the nerve roots in that area, which can lead to symptoms like pain, numbness, or weakness in the legs.
What does paracentral disc herniation at the L5-S1 level causing mass effect upon the left S1 nerve root mean?
It means that the disc between L5-S1 has protruded out to one side (not centrally), and is affecting (most likely compressing) the S1 nerve root which is below the level of the herniation (the L5 nerve root has already exited the IVF). From this report I am assuming you are having some sensory or motor problems in your lower limbs?!
What is displacement of the bilateral L5 nerve roots in the neuroforamen and displacement of the left S1 nerve root as it exits the canal?
The nerves coming off the spinal cord at L5 and S1 are being pushed out of their normal position.
What is encroachment of the neutral foramen on the left at L3-4 atrributed to disc bulging and what is transitional lumbosacral segment at L5-S1 associated with mild disc bulging?
Encroachment of the neutral foramen on the left at L3-4 due to disc bulging indicates that the intervertebral disc is protruding and compressing the nerve root exit point, potentially leading to symptoms like pain or numbness in the corresponding lower limb. A transitional lumbosacral segment at L5-S1 suggests an anatomical variation where the L5 vertebra may exhibit characteristics of the sacrum, which can predispose this area to abnormal stress and mild disc bulging. This bulging may further contribute to nerve root irritation or compression at this transitional segment.
What is right neural foramen?
what is disc protrusion in the right neural foramen abutting right L5 nerve root
What is evidence of impression on the L5 and S1 nerve root on the right ay the L5 S1 level?
Evidence of impression on the L5 and S1 nerve root on the right at the L5-S1 level typically includes imaging findings such as a herniated disc, foraminal stenosis, or a mass effect from adjacent structures. On MRI, this may present as displacement or compression of the nerve roots, along with associated edema or inflammation in the surrounding tissues. Clinical symptoms may also be evident, including radicular pain, numbness, or weakness in the lower extremity corresponding to the affected nerve roots.
What is the spinal root of the tibial nerve?
The tibial nerve arises from the L4 to S3 spinal nerve roots. It is a branch of the sciatic nerve and provides motor and sensory innervation to the posterior leg and sole of the foot.
Sciatica reflects neuritis in a nerve from the?
Sciatica is caused by compression or irritation of the sciatic nerve, which is the largest nerve in the body. This can result in pain, numbness, or tingling that radiates down the back of the leg. Common causes include a herniated disc, bone spur, or muscle imbalance.
Herniation at L4-5 which abuts and displaces the L5 nerve root?
disc is herniated ( sticks out further than what its supposed to meaning it sticks out past your vertebrates) and it has your nerve pinched. I'm going to guess that you have leg pain as well right? lol had the same problems, just had a L5 S1 fusion
