Any Risk of Nerve Damage with Lipoma Removal Near Spine?

Yes it is possible that you have a tumor that extends to the spine. I am not sure how you know that this is a lipoma as it could be another tumor such as a vascular malformation. In this case Cobb's Syndrome is one possible diagnosis. In some cases, an MRI may be indicated to further evaluate or distinguish the nature of the tumor.

any mass or soft tissue tumor located near the spine must be proven not to be a meningomyelocele or an AVM prior to surgical excision.  Most are very easily detected on physical exam. if unsure a mri or ct can be order. An Mri would show you better resolution but a ct would show you grossly whether the tumor involves the spine or not.

A lipoma is a superficial collection of normal fat cells which are growing too fast, thus creating a lump.  Removing a lipoma will damage the nerves in the skin next to it, and you will have skin numbness for a few months.

I agree, however, with the other surgeons, the importance of making sure this is a lipoma.  A lipoma is superficial and easily mobile.  If there is ANY suspicion, an MRI is required to evaluate the mass.

Best of luck.
