Post-traumatic chronic paroxysmal hemicrania (CPH) with aura.

The authors describe a patient who developed chronic paroxysmal hemicrania (CPH) in close temporal relationship to a head injury. The subsequent attacks of CPH were associated with a typical migrainous sensory and motor aura. Administration of indomethacin 75 mg daily resulted in isolated occurrence of autonomic and aura symptoms in the absence of pain symptoms. The patient became completely asymptomatic on indomethacin 100 mg daily. Migrainous aura may be seen with trigeminal-autonomic headaches and may represent the expression of an aura-susceptibility gene rather than typical migraine headache biology.
