My husband has been having low back pain constantly for the last six weeks. The MRI showed an intradural lipoma. What is this?
A lipoma is a benign fat tumor. The term “intradural” tells us its location. The dura is a fibrous covering to protect the brain and spinal cord. Intradural means the tumor is inside this lining. Lipomas are benign, not malignant. This means they stay where they are and don’t travel to other parts of the brain or nervous system. Even so, a benign lipoma can cause problems. If it grows large enough, it can put pressure on nearby nerves or spinal cord. Muscle weakness, changes in sensation, loss of bowel and bladder control, or other symptoms can occur. The lipoma can be removed if it is growing and/or causing problems.
