Reversible cerebral vasoconstriction syndrome is characterized by thunderclap headache associated with multifocal vasoconstriction of cerebral arteries in patients without aneurysmal subarachnoid hemorrhage (SAH). The vasoconstriction reverts within three months. We report a 44-year-old man who had a thunderclap headache during sexual intercourse. ⋯ A new angiography after 15 days was normal. He remains headache-free after twenty six months. In conclusion, patients who have thunderclap headache with normal brain CT and cerebrospinal fluid without xantochromia should be investigated for this syndrome.
