What is sinus of the spine?

Spinal dermal sinus tracts consist of an epithelial-lined tract extending from the skin surface to the spinal fascia, dura mater, or spinal cord. These lesions may be found anywhere along the midline of the neural axis. They result from abnormal ectodermal adhesion of the neural tube to the dermis.

What is dorsal sinus?

Dorsal dermal sinus is an epithelium-lined tract from the skin to the spinal cord, cauda equina, or arachnoid as in a form of spinal dysraphism.

What is pseudo sinus tract?

A pseudosinus tract is a normal fibrous cord extending from the coccyx to an overlying sacral dimple. These have no associated mass and contain no fluid (if CSF drainage is occurring via the sacral dimple, then a true dorsal dermal sinus should be considered).

What is a Coccygeal pit?

A coccygeal pit is a very low lying dimple with the pit pointing towards the coccygeal tip. Dimples can also occur higher up above the gluteal cleft. These lesions are more likely to be associated with discolouration. of skin and a tuft of hair within it.

Are sacral dimples painful?

If it becomes infected, it can become swollen and cause pain. Sometimes pus and blood will ooze from the cyst. A sacral dimple is something you’re born with and a pilonidal cyst is something that develops after birth.

What causes dermal sinus tract?

Dermal sinuses are congenital malformation, which are the subtype of occult spinal dysraphism. They are result from incomplete separation of epithelial and neural ectoderm. Failed disjunction causes persistent tract line between the skin and deeper tissues. Most of cases are located at the lumbosacral region.

Do sacral dimples go away?

Most sacral dimples are completely harmless and do not require treatment.

What is Lipomeningocele?

Lipomeningocele occurs when part of the spinal cord protrudes (sticks out) of the spinal column and forms a sac under the skin. Because the spinal cord does not close completely and it attaches itself to the tissues of the back, the nerves of the spinal canal can be damaged.

What is a low lying Conus?

Low-lying conus medullaris: It refers to a low position of a normal-appearing conus medullaris with respect to the vertebral level. It is usually located between the T12L1 and L1L2 disk level; however, in 6.4% of population it can be found between the upper and middle third of L2.

What is a Filar cyst?

A filar cyst is an incidental finding on neonatal lumbar sonography located in the filum terminale of the spinal cord. It is considered a normal variant and is often confused for a ventriculus terminalis, a smooth dilated cavity of the central canal, located within the conus medullaris.

What does a sacral dimple mean?

A sacral dimple is a small indentation (dent) in the lower back, near the crease of the buttocks. It is a congenital condition, meaning it is there when the baby is born. Most sacral dimples do not cause any health issues. In some cases, a sacral dimple can be a sign of an underlying spinal problem.

What is spina bifida baby?

Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way.

When should I worry about a sacral dimple?

Most sacral dimples are harmless and don’t require any treatment. Sacral dimples that are accompanied by a nearby tuft of hair, skin tag or certain types of skin discoloration are sometimes associated with a serious underlying abnormality of the spine or spinal cord.

What is dermoid sinus in Rhodesian Ridgebacks?

The dermoid sinus in Rhodesian ridgebacks is a congenital defect caused by incomplete separation between the skin and spinal cord, after closure of the embryonic neural tube (16).

What is a sinus tract?

A sinus tract is an abnormal channel that originates or ends in one opening. An orofacial fistula is a pathologic communication between the cutaneous surface of the face and the oral cavity. In the literature, the terms fistulas and sinuses are often used interchangeably.

(si-ring’g-m-‘l-) The presence in the spinal cord of longitudinal cavities lined by dense, gliogenous tissue, which are not caused by vascular insufficiency.

How common are sacral dimples in adults?

Sacral dimples are rare, occurring in up to 4% of the population. The majority of these dimples are minor and do not represent any underlying disease; however, the minority may be a sign of disease, notably spina bifida. Even so, this is usually the spina bifida occulta form, which is the least serious kind.

Can a child have dimples if the parents don t?

Facial dimples are genetically inherited. Since his dad also has dimples, it was pretty much a surefire outcome. Since dimples are a dominant trait, only one parent needs to have them.

What are the 4 types of spina bifida?

There are four types of spina bifida: occulta, closed neural tube defects, meningocele, and myelomeningocele. The symptoms of spina bifida vary from person to person, depending on the type and level of involvement.

What level is the Conus?

The conus medullaris is the terminal end of the spinal cord, which typically occurs at the L1 vertebral level in the average adult. Conus medullaris syndrome (CMS) results when there is compressive damage to the spinal cord from T12-L2.

What are butterfly vertebrae?

A butterfly vertebra (sagittal cleft vertebra or anterior rachischisis) is a sagittal defect in the vertebral body caused by failure of fusion of the 2 lateral chondrification centers during embryogenesis.

What is the Conus?

The conus medullaris is the bundled, tapered end of the spinal cord nerves. Situated near the first two lumbar vertebrae, the conus medullaris ends at the cauda equina, a bundle of spinal nerves and nerve roots. Consequently, problems with the conus medullaris often affect the cauda equina.
