What causes spinal lipoma?

What causes spinal lipoma?

Spine Disorders Lipomas are considered developmental or inclusion tumors because they are caused by an error in fetal development in which normal adipose tissue remains stuck to developing spinal cord tissue. Dermoids and epidermoids are also considered developmental inclusion tumors.

Can a lipoma affect your spine?

Lipoma. A lipoma is a rare growth that begins in fat tissue, usually in the middle of the back, where it may press against the spinal cord. This is a congenital condition, meaning that it’s present at birth.

What is the Filum?

The filum terminale (“terminal thread”) is a delicate strand of fibrous tissue, about 20 cm in length, proceeding downward from the apex of the conus medullaris. It is one of the modifications of pia mater. It is continuous above with the pia mater and contained within a tubular sheath of the dura mater.

What is a spinal cord lipoma?

General Information. A spinal cord lipoma is fat within the normally positioned spinal cord without any skin or bony abnormalities. Most commonly these rare lesions are located within the thoracic spinal cord. They may be symptomatic and appear most often in adults.

Can lipomas cause problems?

They can be annoying and unsightly, but they don’t usually cause problems. Most lipomas don’t need treatment. But if a lipoma causes pain or you’re concerned about its size or location, see your provider.

Can a lipoma become cancerous?

Cancerous tumours of the fat cells are called liposarcomas. They are a type of soft tissue sarcoma. It is very rare for lipomas to turn into a cancerous sarcoma. It is still important to tell your doctor if your lipoma changes in any way or if you get any new lumps.

What is DURA?

Dura: The outermost, toughest, and most fibrous of the three membranes (meninges) covering the brain and the spinal cord. Dura is short for dura mater (from the Latin for hard mother). Epidural means outside the dura. An accumulation of blood outside the dura is an epidural hematoma. Subdural means under the dura.

Is filum terminale the same as cauda equina?

The fibrous extension of the cord, the filum terminale, is a nonneural element that extends down to the coccyx. The cauda equina (CE) is a bundle of intradural nerve roots at the end of the spinal cord, in the subarachnoid space distal to the conus medullaris.

What’s a lipoma made of?

A lipoma is a round or oval-shaped lump of tissue that grows just beneath the skin. It’s made of fat, moves easily when you touch it and doesn’t usually cause pain. Lipomas can appear anywhere on the body, but they’re most common on the back, trunk (torso), arms, shoulders and neck.

Why do people get lipomas?

Lipomas often show up after an injury, though doctors don’t know whether that’s what makes them form. Inherited conditions can bring them on. Some people who have a rare condition known as Madelung’s disease can get them. This most often affects men of Mediterranean ancestry who have alcohol use disorder.

What is the main cause of lipoma?

What causes a lipoma? Healthcare providers aren’t sure what causes lipomas to grow. They are inherited (passed down through families). You’re more likely to develop a lipoma if someone in your family has one.
