Intraosseous venous vascular malformation (formerly hemangioma). a Sagittal and (b) axial CT of the cervical spine showing the thickened vertical trabeculation (arrow) in a background of fatty tissue classically seen in the lesion at C7, described as the “corduroy sign” in the sagittal or coronal planes and a polka-dot appearance in the axial plane. c Sagittal T2WI MR image of the cervical spine in a companion case demonstrates the hyperintense nature of a lesion in the C5 vertebral body due to a fat component
