Vertebral venous channels: CT appearance and differential considerations

DJ Sartoris, D Resnick and J Guerra Jr

A comprehensive study of the anatomy, radiologic images, and pathology of venous channels in the thoracic and lumbar vertebral bodies was performed using cadavers and patients. These structures may be mistaken for fractures, lytic lesions, or other abnormalities on high-resolution axial computed tomographic (CT) scans of the spine. A distinct osseous wall, absence of extension over multiple contiguous levels, lack of displacement, and predominant localization in the mid-axial plane of the vertebral body are characteristic features of venous channels. An understanding of the normal intraosseous venous anatomy should prevent misinterpretation of clinical CT studies in most instances.
