case_images: Preoperative axial (a and b) and sagittal (c and d) T2-weighted magnetic resonance imagings demonstrate a dumbbell-shaped extradural solid mass at the level of L4-L5 neural foramen, causing spinal canal stenosis and compression on the thecal sac and cauda equina nerve roots.

case_images: The lumbar magnetic resonance revealed a dumbbell-shaped, L4 extradural, and solid mass (i.e., 2.2 x 2.1 cm axial diameter) compressing the cauda equina and extending into the left L4-L5 neural foramen [Figure 1].
case_images: Postoperative axial (a and b) and sagittal (c and d) gadolinium-enhanced magnetic resonance imaging demonstrate no evidence of residual tumor.
