This type of headache forces to rule-out critical life-threatening conditions like posterior communicating artery aneurysm among others with neuroimaging test. This conditions has been named Benign Episodic Unilateral Mydriasis (BEUM). We present a clinical case with this characteristics but with the difference that it does not have previous history of migraine like is usual in BEUM.
