Stabbing headache as the presenting manifestation of intracranial meningioma: a report of two patients.

Stabbing headache may occur as a primary headache disorder, may accompany other primary headaches, or, in rare instances, may be associated with secondary headache syndromes. We report two patients with intracranial meningioma in whom stabbing headache was the heralding symptom. Headache remitted promptly following surgical resection. These cases stress the importance of excluding underlying pathology in patients presenting with new-onset stabbing headache.
