Classic migraine with cerebral cortical infarction causing permanent hemianopia.
Southern Medical Journal
|July 1, 1979
Summary
A long-term migraine patient developed permanent vision loss due to a stroke affecting the visual cortex. This case highlights a rare complication of migraine, emphasizing the importance of neuroimaging in diagnosis.
Area of Science:
- Neurology
- Neuro-ophthalmology
- Vascular Neurology
Background:
- Classic migraine with visual aura is a common neurological disorder.
- Long-term follow-up of migraine patients is crucial for identifying potential complications.
- Visual disturbances are hallmark symptoms of migraine with aura.
Observation:
- A patient with a 15-year history of classic migraine with visual aura presented with permanent right homonymous hemianopia.
- The visual field defect indicated a lesion affecting the visual pathways.
- Clinical presentation suggested a potential link between migraine and the new-onset visual deficit.
Findings:
- Computerized axial tomography (CT) revealed vascular infarction or ischemia in the contralateral visual cortex.
- The imaging findings confirmed a stroke as the etiology of the hemianopia.
- The stroke involved the brain region responsible for processing visual information.
Implications:
- This case suggests a potential, albeit rare, link between chronic migraine and cerebrovascular events.
- Permanent visual field defects can occur as a complication of migraine.
- Neuroimaging is essential for diagnosing the cause of new-onset visual deficits in migraine patients.
- Understanding these associations can improve diagnostic accuracy and patient management.
