Work-up, including magnetic resonance imaging of the cervical spine and computed tomographic angiography of the neck, showed ventral cord compression at the C5-6 level as a result of a ventral epidural hematoma [Figure 1].
Left vertebral artery injection, (a) anteroposterior (with inset) and (b) posterior views, demonstrating a very small, posteromedially projecting pseudoaneurysm in the V2 segment (arrows)

Cerebral angiography was performed, which revealed the presence of a 0.5 mm x 0.85 mm pseudoaneurysm in the V2 segment on the left side [Figure 2].
Digital subtraction angiography of the left vertebral artery after the deployment of two Pipeline embolization devices (a, anteroposterior; b, lateral). Previously seen pseudoaneurysm is no longer visible (arrows)

Follow-up angiography 4 days later demonstrated no evidence of residual pseudoaneurysm [Figure 3], and the patient's quadriparesis gradually improved over the next week.
