Magnetic resonance imaging revealed lipoma of the filum terminale (hyperintense sign within the filum terminale) (Figure 1).
Operative findings surgical features: exposure of the dural sac (A), observe the lipoma of the filum terminale (arrow) and after dural sac open (B). Lipoma filum terminale (C), neurophysiological monitoring (D): tracings demonstrating amplitude of the wave and the number of stages before (continuous arrow) and after (dashed arrow). An increase was observed in amplitude of wave number and phase after resection of the lipoma of the filum terminale

The patient underwent surgery without delay with intraoperative neurophysiological monitoring (Figure 2), and she had a full recovery of all neurological deficits.
