CTICasesDog Bite Injury with Vertebral Artery Pseudoaneurysm
Imaging findings
CT neck angiography following a severe dog bite shows extensive soft tissue gas in the neck, fractures of the left C5 and C6 transverse processes, and a focal pseudoaneurysm of the left vertebral artery within the transverse foramen.
Key takeaways
High-impact animal bites (especially dog bites to the neck) can cause deep tissue penetration leading to neurovascular and skeletal injury. Fractures of the cervical vertebral transverse processes must prompt evaluation of the vertebral arteries for dissection or pseudoaneurysm formation.
