The mass measured 14 x 11 x 10 cm; it was seen distorting the sacrum and widening the sacral foramina (Figure 2).

On T2 weighted images, linear and wavy hypointense areas were noted within the mass, suggesting nerve roots and fibrous strands (Figures 3-5).
(a) Sagittal T2 weighted image showing a heterogeneously hyperintense mass in the sacral region extending posteriorly through the sacral foramina. (b) Coronal gradient recalled echo image showing hypointense linear areas within the mass.
