Cluster headaches are characterized by unilateral sudden onset of intense, brief, sharp pain along the side of the face around the eye. Patients often can have symptoms that are resistant to medications, nerve blocks, and surgical treatments. There is increasing evidence of anatomical and functional connections between the trigeminal and occipital nerves. We present a patient with cluster headache presenting with chronic ipsilateral facial pain with nasal congestion and left eye pain who achieved sustained pain relief with an ultrasound-guided injection into the pterygopalatine fossa in conjunction with an ultrasound-guided pulsed radiofrequency ablation procedure involving the C2 dorsal root ganglion.
