Preoperative sagittal T2-weighted magnetic resonance imaging (MRI) without contrast (a) and axial T2-weighted MRI scan without contrast (b) demonstrate an extradural T2 hypointense lesion in the dorsal epidural space at the level of L2-L3 with severe thecal sac compression (white arrow).

The lumbar MRI revealed a posteriorly located extradural lesion at L2-L3 with compression of the thecal sac, thought to represent an extradural tumor [Figure 1].

Preoperative sagittal T2-weighted magnetic resonance imaging (MRI) without contrast (a) and axial T2-weighted MRI scan without contrast (b) demonstrate an extradural T2 hypointense lesion in the left dorsal epidural space at the level of L5-S1 with compression of the thecal sac and left S1 nerve root (white arrow).
