The narrowing of a thecal sac depends on where it is located. It might be a bulging disc or a pinched nerve.
A thecal sac deformity is usually associated with a herniated disc, however some thecal sac deformities are congenital. If the deformity is associated with a herniated disc, surgery may be recommended.
Spinal cord is covered by 3 layers and between it's 2 layer there is fluid know as csf. The spinal cord along with it's 3 layers is known as thecal sac. The above thing is a MRI finding in which the disc is just indenting the thecal sac without any compression of the neural elements. This is a insignificant finding and patient should not have any symptoms. The ventral side means the front side and the dorsal side means the back side.

The correct word is thecal sac which is located witin the spinal vertebra. It is made up of a mixture of pia-mater-wrapped lumbar, sacral and coccygeal nerve roots and it protects these roots. The nerve roots of the thecal sac float freely in cerebral spinal fluid (CSF) which provides both protection and nutrition for the roots.
Thecal sac flattening occurs when a herniated disc has into the spinal canal that it is pushing on the thecal sac. The thecal sac is the membrane of dura mater that surrounds the spinal cord and the cauda equina.
These results on an MRI report mean a few different things. First is that there is generalized bulging of the lower discs of the neck. Second is that there bone spurs which have grown which are putting pressure on the thecal sac which can cause symptoms severe enough to require surgery in some cases.
The thecal sac is a normal part of the human anatomy and doesn't need to be cured.
The thecal sac is a normal part of the human body. It is not a condition that needs to be cured.
The anterior thecal sac is a membrane that surrounds the spine. It acts as protection to the spinal cord and the cauda equina.
The thecal sac is the covering for the spinal cord. This can be seen on an MRI. Impingement means that something is pressing on it.
The lumbar thecal sac is a membrane that surrounds the spinal cord. It is filled with cerebral spinal fluid. It is in the lower back.
