Subdural Lipoma of Cauda Equina

Lipomatous tumors of the central nervous system are generally considered as maldevelopmental origin. They can occur anywhere along the entire neural axis. Lipoma of the spinal cord is rare benign tumor occuring predominantly in cervical and thoracic cord. The incidence was reported 1% of all primary intraspinal tumors. The first intrameduallary lipoma in conus of spinal cord was reported by Gower in 1876. Review of literature concerning intradurallipoma done by Ehni and Love (1945) listed 29 cases un til 1945. Caram et al collected 51 cases un til 1957 and recently Giuffre listed 100 cases of this tumor in 1966. The case presented here is a surgically rem oved subdural lipoma arising in cauda equina. The surgical removal was very difficult because of infiltration into the cord and entangling with nerve roots
