BACKGROUND: Inadvertent cannulation or penetration of the cervical radicular arteries during cervical transformaminal epidural injections (TFESIs) is a serious clinical risk, and purportedly, the cause of possible spinal cord injury sustained during this procedure. CASE: Here, we present a case of inadvertent intravascular penetration of a cervical radicular artery during a C5-6 TFESI and demonstrate the best image capture to date of direct ramification of a cervical radicular artery into the anterior spinal artery. CONCLUSION: This observation reinforces the need for contrast injection and real-time digital subtraction fluoroscopy during cervical TFESIs for the prevention of spinal cord injury and fatalities.
