Summary
MR images of four patients with a thickened filum terminale showing a fat signal are presented. There were no related symptoms and no evidence of tethering. The thickened fatty filum terminale seemed to be a developmental anomaly and without clinical significance. As the incidence of this anomaly was 0.24% in our series, knowledge of its possible presence of this anomaly is important for routine reviews of MR image.
