AbstractVertebral artery tortuosity causing neural foraminal widening is a well described abnormality that should not be confused with other causes of neural foraminal enlargement, particularly on conventional roentgenograms. We, hereby, describe CT features of another cervical osseous change due to the vertebral artery tortuosity, the so called "tubular shaped vertebral artery canal", which is embedded in the vertebral body instead of causing neural foramen enlargement. Catheter and MR angiographic studies have also been performed to confirm the vertebral artery tortuosity causing the osseous changes.
