Lumbosacral spine MRI showed L4-L5 posterior extradural compression with peripheral contrast-enhancement on T1-weighted sagittal and axial sequences (a and b) and hypointensity on T2-weighted sagittal and axial sequences (c and d).

T1-weighted sequences and hypointense on T2-weighted sequences); it markedly enhanced with contrast (Gadolinium DTPA) [Figure 1]. The differential diagnoses included: tumor, cyst (synovial and ligamentum flavum), and disc.
Hematoxylin-eosin staining confirmed the disco-ligamentous nature of the disc sample.

A left-sided hemilaminectomy was performed at the L4-L5 level and revealed atypical, extruded disc fragment that was microsurgically removed [Figure 2].
