Five cases of fatty filum terminale were encountered in a retrospective analysis of 332 routine lumbosacral magnetic resonance studies. The T1-weighted and GRASS images were particularly useful in evaluating the filum. An irregularly thickened fatty filum, especially if associated with a low conus, is likely to be pathologic and responsible for a patient's symptoms and signs.
