Transforaminal epidural steroid injection (TFESI) is a conservative method to treat back pain due to radiculopathy. However, epidural hematoma can occur after the procedure by various mechanisms, which can cause serious complications.
Emergency magnetic resonance imaging revealed fluid collection in the posterior epidural space at the T11-L1 level with central-canal stenosis.
Emergency hematoma evacuation was performed to remove the epidural hematoma.
After the surgery, the back pain disappeared.
Epidural hematoma may occur due to causes other than direct needle injury after TFESI. Therefore, careful observation of the patient is necessary after the procedure.
