TETHERED CORD SYNDROME PART 2: LIPOMATOUS STRUCTURES
LIPOMATOUS CAUSES OF CORD TETHERING
A tethered cord can be caused by a number of abnormalities.
- Fatty Filum and Lipomas
- Spinal dysraphism
- Diastematomyelia
- Caudal regression and sacral agenesis.
- And a condition called a Tight Filum Syndrome or Occult Tethering.
This post looks at two abnormalities
- Fatty Filum
- Spinal Lipomas particularly of the Conus / Filum and distal thecal sac.
| FATTY FILUM |

| SPINAL LIPOMAS |
|
Spinal Lipomas are a common cause of tethering
Image Above: Intra dural extra medullary lipoma ( blue arrows)surrounding the conus . The lipoma will have nerve roots traversing through it. No tethering as conus lies in normal position.
