intramedullary spinal cord lipoma

Wednesday 21 December 2011

Intramedullary spinal cord lipomas not associated with dysraphism are infrequently reported. When present, they typically occur in children and have a predilection for the cervical and thoracic spinal cord.

In addition to a decompressive laminectomy, debulking of the lipoma provides the best long-term neurological outcome. Gross-total excision is not warranted and usually is not possible.

Long-term follow-up is needed, and repeat debulking of the lipoma is indicated if there is an increase in tumor size due to hyperplasia of residual adipocytes, when tumor growth is associated with neurological deterioration.

Types

- dysraphic intramedullary spinal cord lipoma
- non-dysraphic intramedullary spinal cord lipoma
