Anterior vertebral wall vascular groove vs. fracture. (a) Lateral radiograph shows a typical linear indentation (arrows) at mid-anterior vertebral body wall representing a vertebral artery groove, in a 1.4 year-old girl treated with glucocorticoids for juvenile inflammatory arthritis. This is unlikely to be confused with fracture. (b) Lateral radiograph shows residual indentation (arrows) at anterior vertebral body walls from ossifying vertebral artery grooves in a 5 year-old girl, with. (c) In this anterior wedge compression fracture (arrow) in a 7 year-old boy with linear flattening of endplates, the indentation of anterior cortex is similar to image (b) and may be incidental. The children in (b) and (c) were both treated with glucocorticoids for acute lymphoblastic leukemia
