12-year-old male with hematuria and flank pain following blunt trauma to the right flank after MVA. Axial CT through the kidneys shows a delayed nephrogram and multiple ill-defined filling defects in the right kidney consistent with contusions and possible vascular injury. An associated fracture of a right transverse process is noted with swelling of the ipsilateral erector spinae muscle and psoas muscle at that level.
