Presentation
Right-arm pain. TFESI for diagnostic/therapeutic injection.
Patient Data
Age: 50 years
Gender: Male
Axial Post-contrast injection

Injection of a small amount of iodinated contrast through a 25-gauge Quincke needle extends through the right C6-C7 foramen with epidural extension.
Case Discussion
The aim of a TFESI is to position the needle tip close to the targeted foramen so that the injectate will extend through the foramen into the epidural space. The ipsilateral vertebral artery is one of the key structures to consider when both planning for and undertaking the procedure.
