Aggressive Vertebral Hemangioma

Evidence of altered signal intensity involving the L2 vertebral body appearing hyperintense on both T1 and T2 weighted images with striated appearance, mild posterior convexity , epidural & right paravertebral extension. Characteristic polka dot appearance is noted on axial images.  Imaging characteristics likely indicate aggressive hemangioma, with extensions as described.  Vertebral hemangioma (VH) is virtually vascular malformation, which is usually asymptomatic. Only 3.7 % of VH may become active and symptomatic, and 1 % may invade the spinal canal and/or paravertebral space.
