title: Unusual MR presentation of occult spinal dysraphism with lumbosacral lipoma and dermoid cyst.
abstract: METHODS
  We describe a case with tethered cord syndrome due to the association of intradural lipoma and a dermoid cyst at the filum terminale that had an unusual magnetic resonance (MR) appearance.
  
  
  CONCLUSIONS
  Although both pathologies usually demonstrate a similar intensity on MR images, the involvement of a capsule filled with hair in the dermoid cyst, which presented hypointensity, may be a clue to be differentiated from lipoma on preoperative MR images.
