Orgasmic headache with transient basilar artery vasospasm.

A 36-year-old man without significant past medical history presented with recurrent explosive headache at the time of orgasm. Magnetic resonance angiography showed focal mid-basilar artery narrowing. Despite receiving no specific therapy, the patient's headaches and vascular narrowing had resolved completely on follow-up six months later. While a number of pharmacologic agents have been proposed to be of benefit in orgasmic headache, this case suggests that spontaneous resolution may also occur.
