Summary

Vertebral artery tortuosity can cause a unique "tubular shaped vertebral artery canal" within the cervical spine. This osseous change, distinct from neural foraminal widening, is identified via CT imaging.

Area of Science:

  • Radiology
  • Anatomy
  • Medical Imaging

Background:

  • Vertebral artery tortuosity is known to cause neural foraminal widening.
  • This widening can be mistaken for other causes of neural foramen enlargement on conventional roentgenograms.
  • A less common osseous change associated with vertebral artery tortuosity exists.

Purpose of the Study:

  • To describe the computed tomography (CT) features of a distinct cervical osseous change.
  • To identify the "tubular shaped vertebral artery canal" associated with vertebral artery tortuosity.
  • To differentiate this finding from neural foraminal enlargement.

Main Methods:

  • Computed tomography (CT) imaging was used to visualize cervical osseous changes.
  • Catheter angiography was performed to assess vertebral artery anatomy.

Related Experiment Videos

  • Magnetic resonance (MR) angiography was utilized to confirm vertebral artery tortuosity and associated osseous changes.

    • Main Results:

    • A "tubular shaped vertebral artery canal" embedded within the vertebral body was identified.
    • This finding is a consequence of vertebral artery tortuosity.
    • The "tubular shaped vertebral artery canal" does not cause neural foramen enlargement.

    Conclusions:

    • Vertebral artery tortuosity can lead to the formation of a "tubular shaped vertebral artery canal" within the cervical vertebral bodies.
    • This osseous change is a distinct entity and should not be confused with neural foraminal widening.
    • CT imaging is crucial for identifying this specific anatomical variation.
