Pericarotid cluster headache.
Cluster headache is generally not associated with recognised disease, and the pathogenesis remains unclear. The onset of typical cluster headaches is reported in a patient with nasopharyngeal carcinoma. The tumor encircled the internal carotid artery but did not extend intracranially. It thus appears possible that cluster headaches may be triggered by processes involving the carotid artery.
