case_images: Plane CT neck in bone window algorithm, axial and sagittal views (a and b); enhanced CT neck in soft tissue algorithms, axial and sagittal views (c and d).. a and b: Vertebral fracture of C2 and dislocation between C2 and C3 . c and d: Marked extravascular leakage was seen on the anterior surface of the vertebral body (white dotted line), in the spinal canal of the cervical spine, and on the posterior surface of the vertebral body (white arrow).

case_images: Angiography of the vertebral artery. The main trunk of the vertebral artery is open, with no dissection. Two radicular arteries from V2 and V3 show significant extravascular leakage (black arrows).

case_images: The main trunk of the vertebral artery was open, with no dissection, but two radicular arteries from V2 and V3 showed significant extravascular leakage (Figure 2).
case_images: a/b Angiography of radicular artery. (a) Coronal view; (b) Sagittal view. The sagittal view shows bleeding to the anterior surface of the vertebral body; this is caused by extravascular leakage from the radicular artery (black arrows).

case_images: Imaging during contrast infusion was performed in sagittal view and bleeding to the anterior surface of the vertebral body was consistent with extravascular leakage seen on the CT image (Figure 3).
case_images: Angiography of another radicular artery. a) Additional oblique imaging to identify the remaining radicular artery more clearly. Changing to a smaller-diameter catheter allows selection of the responsible vessel. The oblique view of the origin of the radicular artery makes it easier to visualize and catheterize the artery for selection.. b) This vessel was similarly embolized using lipiodol + NBCA (4:1).

case_images: Additional oblique imaging was used to identify the involved branches more clearly (Figure 4a). The branch vessel was similarly embolized using lipiodol + NBCA (Figure 4b).
case_images: Angiography of the vertebral artery after TAE. Extravascular leakage at the relevant site has disappeared.

case_images: Angiography of the left vertebral artery. Traumatic arteriovenous fistula is present, but no extravascular leakage is evident.
