Migraine precipitated by head trauma in athletes.

Abstract

To present the clinical features of a case of migraine precipitated by head trauma. Detailed history was obtained and ophthalmic and neurologic examinations were performed. This patient's history of transient loss of vision followed by severe headache precipitated by a direct blow to the top of the head is characteristic of this phenomenon. Normal neurologic and opthalmic examination findings, normal magnetic resonance imaging, and a history of similar episodes are all consistent with this diagnosis. Familiarity with this entity can obviate an expensive examination for patients with these classic symptoms.
