What is compression of the ventral dural sac?
to touch the spine
The dural sac covers the spine. Typical causes of dural sac impingement typically include bulging discs, herniated discs, or osteophytes. These conditions can also affect the spinal cord.
S3
Thecal sac flattening refers to a condition where the thecal sac, which surrounds the spinal cord and nerves, is compressed or narrowed. This can occur due to various reasons such as disc herniation, spinal stenosis, or injury, leading to potential symptoms like back pain, numbness, or weakness in the extremities. Treatment may involve addressing the underlying cause, physical therapy, or in severe cases, surgical intervention.
dural folds
You have a bone spur on the vertebrae that is protruding towards the front of your body and putting pressure on the sac of cerebrospinal fluid that encircles the brain and spinal cord.
Ventral means in front. Thecal sac means the sac that contain the spinal cord and cerebro spinal fluid. Effacement of the ventral thecal sac means pressure is upon the front of the sac (producing a flattening effect) most likely from a disc protrusion. Foramen means hole (where the nerve comes out of from the spinal cord). Stenosis means narrowing (usually from bony degeneration or disc herniation/protrusion/or bulge). Left foraminal stenosis means narrowing of the passageway where the nerve comes through.
Flattening of the Pons is typically associated with several neurological conditions causing autonomic dysfunction.
It means a piece of your disk has broken off completely form the rest of the disk, and it is pressing on a nerve root that branches off from your spinal cord.
