title: [Sentinel headache: a premonitory symptom too often unrecognized in intracranial ruptured aneurysm].
abstract: Headache is a common complaint in emergency departments, but only a small percentage of patients have a serious disease. Nevertheless, some forms of headache, such as "warning headaches", need special attention. By far the most common symptom associated with aneurysmal minor bleed (warning leak) is a sudden headache that is considered to be a warning symptom of impending aneurysmal rupture. In the presence of sudden severe headache with or without meningeal signs or nausea, subarachnoid hemorrhage should always be considered. Recognition of these warning headaches probably offers the best opportunity of reducing the otherwise serious mortality and morbidity of aneurysmal subarachnoid hemorrhage. This report describes 7 non-consecutive patients presenting warning headaches before major aneurysm rupture. Based on our experience and a review of the literature, we recommend a management algorithm for patients presenting with sudden severe headache.
