T6-10 left lateral thoracic meningocele with complex dural folds. Markedly distorted spinal cord with reduced volume, cord displaced anteriorly and to the left. Nerve rootlets can be seen transversing the fluid space to reach the right side. Lateral expansion of meningocele through left T8/9 and T9/10 foramina.
Lipoma/entrapped fat seen on dorsal aspect of the cord at the superior aspect, forming a "placode-lipoma interface" within the spinal canal. Lipoma is contiguous with posterior epidural fat, and has a circumferential dural envelop (which becomes thickened and more obvious post-shunting - not shown).
T8 and T9 posterior vertebral body scalloping. Marked enlargement of T9/10 left foramen, lesser degree T8/9.
No lumbar spinal dysraphism. Conus tapers normally at L1. (Lumbar MR images not shown).
No stigmata of NF-1 or Marfan syndrome. No scoliosis.
