5-year-old female patient with tethered cord repair, lipomyelomeningocele, yearly MRI. Evaluate for change. Thoracic Spine:Vertebral body heights and disc spaces are within normal limits with anatomic alignment. Bone marrow signal is normal. There is no thoracic cord signal abnormality.Lumbar Spine:There are postoperative findings related to attempted detethering of the filum terminale. Redemonstration of lipomatous mass centered along the dorsal aspect of the thecal sac that extends from the level of L3-S1. This mass has decreased in thickness now measuring 7 mm in maximal thickness, previously 9 mm. The conus medullaris is low in position, distorted, and terminates within the lipomatous mass, unchanged. The cord remains tethered along the dorsal aspect of thecal sac with prone imaging. The lower lumbar and upper sacral vertebral posterior elements are absent.Vertebral body heights and disc spaces are otherwise normal in height and in anatomic alignment. Bone marrow signal is normal. The lower lumbar dorsal subcutaneous fat is prominent, but does not appear to communicate with the intrathecal lesion, unchanged.
Post-operative changes of the lumbosacral spine with a tethered spinal cord and decreased size of an associated intraspinal lipoma.
