MR-angiography during spontaneous attacks of cluster headache: a case report.
Magnetic resonance (MR) angiography was performed during and between two spontaneous and untreated attacks in a 24-year old male patient with episodic cluster headache. The ipsilateral ophthalmic artery was observed to be markedly dilated during both attacks. No changes were seen in the internal carotid artery or any of the main arterial branches on either side. A repeat MR-angiography two weeks later when the patient was in clinical remission showed no abnormalities. Our present case report suggests that the MR technique provides a useful method for non-invasive angiography during spontaneous attacks of cluster headache.
