Thecal Sac Thecal sac is the layer that protects the spinal cord. It is filled with cerebrospinal Fluid and has numerous nerve roots Thecal sac is the layer that protects the spinal cord. It is filled with cerebrospinal Fluid and has numerous nerve roots. Thecal sac is enclosed in the Dura Matter. Dura matter is the outer layer which covers the central nervous system, which includes the brain and spinal cord 1. Thecal sac varies in both genders.

What is a thecal sac? Answers. Best Answer: Hi Kevin. The thecal sac is the connective tissue that surrounds the spinal cord. The report is saying that you have some compression of this outer part of the cord. Effacement means 'touching', so the large disk protrusion at L5-S1 is touching the S1 nerve root.nswers.

Foraminal Stenosis Definition If you have foraminal stenosis, knowing the definition of the condition can be helpful as you consider your treatment options. In general terms, “foraminal stenosis” refers to the narrowing of the canals in the vertebrae that are responsible for protecting the nerve roots as they exit the spinal column. This constriction can disrupt regular nerve function and result in pain and other pain-related symptoms.

What Is Spinal Stenosis? In this Article. Spinal stenosis is a condition, mostly in adults 50 and older, in which your spinal canal starts to narrow. This can cause pain and other problems. Your spine is made up of a series of connected bones (or “vertebrae”) and shock-absorbing discs. It protects your spinal cord, a key part of the central nervous system that connects the brain to the body. The cord rests in the canal formed by your vertebrae.

Understanding and Treating Spinal Stenosis CT or CT myelography is useful in patients who have a contraindication to magnetic resonance imaging (MRI) scan (pacemaker, metallic implants, etc.). On CT, midsagittal lumbar canal diameters of less than 10 mm are regarded as an absolute stenosis while less than 13 mm represents relative stenosis.23.

Spina bifida Spina bifida. (Redirected from Sacral defect anterior sacral meningocele) Spina bifida is a birth defect where there is incomplete closing of the backbone and membranes around the spinal cord. There are three main types: spina bifida occulta, meningocele, and myelomeningocele. The most common location is the lower back, but in rare cases it may be the middle back or neck.

Spinal Stenosis Imaging Spinal stenosis is a progresive narrowing of the spinal canal that occurs most commonly in the cervical and lumbar areas.The prevalence of lumbar spinal stenosis is about 9.3%, with people in their 60s and 70s most commonly affected. Consensus criteria are needed to define and classify spinal stenosis. The means by which spinal stenosis is diagnosed is also changing. Concerns related to radiation risk of CT scans and the recognized limitations of spinal radiography suggest that MRI represents the best imaging modality in many cases. MRI helps avoid myelography and the associated risk and pain.

Spinal Stenosis Causes, Symptoms, and Treatment What Is Spinal Stenosis?

What does effacement of the left ventral thecal sac and possible minmal flattening of left central cervical spinal cord at c5-c6 Left framinal stenosis particularly proximal at this level mean? 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).

Foraminal narrowing overview Foraminal narrowing, or foraminal stenosis, is a condition of the spine that can cause pain and other symptoms resulting from spinal nerve root compression. At every level of the spine, a pair of nerve roots runs through the spinal column via small openings called foramina (singular: foramen). When narrowing, or stenosis, occurs in the foramina, the space available for the nerve roots to pass is reduced.

- Uncomplicated mechanical stenosis may occasionally be relieved with simple probing, but severe cases (often following bacterial infection of the lacrimal sac) are treated surgically: a dacryocystorhinostomy is performed to anastomose the mucosa of the nasal cavity to the lacrimal sac through an osteotomy made in the lacrimal bone. 15

- Impress means to indent or affect. Ventral refers to the front, the opposite of posterior. Thecal sac is the outer covering of the spinal cord. This means there are bone spurs on the back of the spinal bones, putting pressure on or affecting the front part of the outer layer of the (neck) cervical spinal cord.his is a common term you may encounter reading your MRI report. Diffuse cervical bulge means a generalized disc bulge of one of spinal discs of the neck (cervical spine). This bulging material may contact or pinch the thecal sac or nerve roots.

Other People Are Reading.oraminal Stenosis vs. Central Stenosis. Stenosis most commonly occurs in two ways: central stenosis, which is the narrowing of the entire spinal canal, and foraminal stenosis, a narrowing of the foramen through which the nerve root exits the spinal canal.
