Reversible cerebral vasoconstriction syndrome is characterised by severe thunderclap headache with associated characteristic transient, multifocal, segmental vasoconstriction of cerebral arteries lasting several weeks to months. We describe a 50-years old woman who presented with a severe sudden onset occipital headache. Neuroimaging revealed segmental vasospasm affecting the intracerebral arteries. The pain improved gradually over the next 6 weeks. Repeat brain MR angiography at 12 weeks showed complete resolution of the segmental narrowing.
可逆性脑血管收缩综合征的特征是严重的霹雳样头痛，并伴有特征性的脑动脉短暂、多灶性、节段性血管收缩，持续数周数月。我们报告一名50岁女性，出现严重突发枕部头痛。神经影像学检查显示节段性血管痉挛累及脑内动脉。疼痛在接下来的6周内逐渐改善。12周时重复脑磁共振血管造影显示节段性狭窄完全消失。
