A lumbosacral spine x-ray showed age-related mild to moderate cartilage degeneration (Fig. 1). 
Magnetic resonance imaging T1 weighted view. a A sagittal scan shows hypertrophy of epidural fat predominately located posterior from L5 to S1 level. b A axial scan of L3-L4 revealed excessive amount of fat within the epidural space compressing the thecal sac. A high signal intensity lesion corresponds to fat (white arrows)

The magnetic resonance imaging (MRI) revealed an epidural mass located at the posterior aspect of the spinal canal extending from the level of L3 to S1 (Fig. 2a). T1-weighted images, compatible with fat. The axial image demonstrated an epidural fat compression of the thecal sac (Fig. 2b).
