CT showed an L2 compression fracture with intravertebral cleft formation (a) and MRI indicated an area of hypointensity on T1 and hyperintensity on T2 and T2-fat suppression images (b, c, d, red arrow). MRA revealed that both sides of the L2 segmental arteries were occluded (e). Unilateral vertebroplasty was performed for the patients (f). The augmented vertebra collapsed and the cement was displaced half a year after the procedure (g)Back to article page
