After interdisciplinary consent, a male patient in his 50s received endovascular treatment of an innocent supraophthalmic aneurysm of the internal carotid artery with a WEB (woven endo bridge) device and stenting. In the medical history, a migraine with aura was reported. A week after intervention, the patient developed an ipsilateral cluster-like headache responsive to classical interventions. Inflammation of the carotid wall near the stent was demonstrated to be associated with the headaches and was responsive to steroid treatment. The presented case demonstrates that postinterventional headache comprises more headache entities than the often reported migraine and tension-type headache with a considerable impact on the patients’ quality of life. The case supports the vascular hypothesis of cluster headache pathophysiology, potentially contradicting current models and assumptions.
