Hemicrania continua, a rare headache disorder, can present with visual aura. This case report details a patient experiencing visual disturbances alongside typical hemicrania continua symptoms, suggesting shared mechanisms with other headache types.
Area of Science:
- Neurology
- Headache Medicine
Background:
- Hemicrania continua (HC) is a rare primary headache disorder.
- It is characterized by persistent unilateral pain, cranial autonomic symptoms, and responsiveness to indomethacin.
- While aura is known in cluster headaches, it's rarely reported in HC.
Observation:
- A 53-year-old man presented with chronic right-sided headache with superimposed severe exacerbations.
- Diagnosis of HC was confirmed by exclusion of secondary causes and complete response to indomethacin.
- The patient experienced transient visual disturbances resembling scintillating scotoma during a pain exacerbation.
Findings:
- This case documents the occurrence of visual aura in a patient with hemicrania continua.
- The patient's symptoms align with established criteria for HC, including response to indomethacin.
- The visual aura episode occurred during a severe pain exacerbation.
Implications:
- This report supports a potential link between hemicrania continua and visual aura.
- It suggests shared pathophysiological mechanisms between HC and other trigeminal autonomic cephalalgias.
- Further research may elucidate the connection between HC, aura, and underlying neurological pathways.
