Cervical epidural corticosteroid injections are frequently used for the treatment of subacute cervicobrachial pain. This therapy isconsidered safe with the vast majority of the complications being minor and transient.
We present a case of a woman in her fifties who suffered from cervicobrachialgia and received 2 cervical epidural corticosteroid infiltrations. On day 3 after the second infiltration, a new headache appeared and on day 16 a bilateral subdural hematoma was visualized on CT scan. Complete resorption of the hematoma was seen on day 25 without surgical intervention.
Up until now, only one case report of anintracranial subdural hematoma after a cervical epidural steroid injectionhasbeen published. But several cases of an intracranial subdural hematoma after spinal, epidural or combined spinal and epidural anesthesia have been reported. Physicians should be aware of this potentially dramatic complication since post-dural puncture headache after any type of procedure can evolve into a subdural hematoma. Clinical differentiation between the two can be difficult,post-dural puncture headache is characterized by relief of symptoms in the supine position and photophobia/phonophobia. A subdural hematoma shouldbe considered ifthe headache changes in character, does not respond to treatment, or there are neurological signs asnausea/vomiting and blurred vision. Immediate medical imaging should then be performed.
