title: Unusual headaches.
abstract: Headache represents one of the most common somatic complaints seen in the emergency department, accounting for 1% to 3% of all emergency department visits. Although most headaches seen in the emergency department are benign, as many as 10% of all headaches are secondary to an underlying pathologic condition. The emergency physician is well-trained to exclude stoke, subarachnoid hemorrhage, and meningitis as potential causes of headache. This article focuses on seven unusual headache syndromes, all of which are associated with significant morbidity and mortality. Particular emphasis is placed on clinical features and diagnostic modalities of choice.
