Abstract
Intradural spinal lipomas that are not associated with spinal dysraphism are rare. Over a 2-year period, a 51-year-old male, developed numbness and muscle atrophy of the lower extremities. Plain roentogenograms showed no abnormalities. Conventional myelography showed an intramedullary spinal cord tumor in the thoraco-lumbar junction. CT myelography showed a low density mass lesion at the right dorsal aspect of the spinal cord. MRI showed a high intensity mass on both T1- and T2-weighted images. A sagittal section clearly showed a mass that was present at the dorsal aspect of the Th12-L1 level. The lesion was histologically comfirmed to be a lipoma.
Neurological improvement was obtained after partial removal of the lipoma.
