T2 weighted MR images show disc bulging and spinal stenosis of L2-3, L3-4, and L4-5 (line) intervertebral spaces (A). Axial view of T2 weighted MR images at L4-5 intervertebral space shows compressed spinal cords due to spinal stenosis (B). Perineural cyst located on the S2 level is typically seen as well circumscribed and ovoid in shape (arrow, C and D). Water density structures of a cyst appear black in T1 weighted MRI (C) and white in T2 weighted MRI (D).
