Case Discussion

Lipoma of filum terminale is a consequence of mesodermal cells migration error during embyogenesis.

As any adipose lesion it is best seen on T1 sequences.

In most cases lipoma of filum terminale is incidental finding of no clinical significance, however association with tethered cord syndrome is described in literature.
