What is central stenosis?

What is central stenosis?

Central stenosis occurs when the central spinal canal is constricted with enlarged ligament and bony overgrowth, causing compression of the spinal cord and cauda equina. Stenosis can occur along any area of the spine (cervical, thoracic, lumbar), but is most common in the lumbar area.

What is moderate neural Foraminal narrowing?

Neural foraminal stenosis refers to the narrowing of the small openings between each vertebra in the spine, called foramen, which nerve roots pass through. A type of spinal stenosis, neural foraminal stenosis, does not always cause symptoms. But if a nerve gets compressed in the gap, this will be painful.

What is moderate lateral recess stenosis?

Between the vertebrae of the spine, there are openings through which the spinal nerve roots pass to exit the spinal column, called foramen. Foraminal stenosis is a condition in which one or more of the vertebral foramen narrows, impinging on or “pinching” the spinal nerve roots.

What causes an indentation in the ventral thecal sac?

Ventral thecal sac indentation refers to parts of the vertebrae or spinal discs pressing on the front side of the thecal sac, causing indentations. Indentations into the thecal sac can result in pain or weakness as they pinch the nerves in the spinal cord. Disc fragmentation in the spine can also affect the thecal sac.

What is the ventral side of the thecal sac?

The ventral thecal sac refers to the ventral, or front side of the thecal sac, which is a membrane that surrounds the spinal cord and some cerebrospinal fluid. A diagnosis of spinal injury and disease takes the appearance of the thecal sac into consideration. The thecal sac consists of dura mater,…

What causes pain and weakness in the thecal sac?

Indentations into the thecal sac can result in pain or weakness as they pinch the nerves in the spinal cord. Disc fragmentation in the spine can also affect the thecal sac. Although it is not common, if a disc ruptures, fragments may rupture the thecal sac.

Which is part of the brain contains the ventral thecal sac?

This membrane is the outermost of the three membranes that surround the brain, and it also encompasses the arachnoid mater and pia mater. Ventral thecal sac indentation refers to parts of the vertebrae or spinal discs pressing on the front side of the thecal sac, causing indentations.

Is the ventral thecal sac part of the spinal cord?
