Nondysraphic intramedullary lipoma

A nondysraphic intramedullary lipoma is a type of benign tumor that occurs within the spinal cord. It is considered “nondysraphic” because it is not associated with a congenital defect in the spine, and “intramedullary” because it is located within the spinal cord tissue itself.

Nondysraphic intramedullary lipomas are relatively rare, accounting for only about 1-2% of all spinal cord tumors. They are composed of mature adipose (fat) tissue and are usually slow-growing. Symptoms can include back pain, weakness, numbness, and difficulty with coordination or balance.

Treatment for a nondysraphic intramedullary lipoma typically involves surgical removal, although in some cases, observation may be recommended if the tumor is small and not causing significant symptoms. In general, the prognosis for these tumors is good, as they are benign and tend not to recur after successful surgical removal.
