Stroke from other etiologies masquerading as migraine-stroke
1Clinical Investigative Stroke Unit, University Hospital, University of Saskatchewan, Saskatoon, Canada.
Abstract:
There has been a recent increase in the number of studies dealing with migraine-stroke. I describe five patients in whom migraine-stroke was the clinical diagnosis but in whom the subsequent clinical events or autopsy showed a different mechanism for the cerebral infarction. Three patients had arterial dissection (one proven at autopsy), one had marantic endocarditis that had been missed on two echocardiograms (proven at autopsy), and one had generalized atherosclerosis and diabetes. These patients demonstrate that important and different etiologies may produce what seems to be the migraine-stroke syndrome. The result may be failure to recognize specific therapeutic measures that could have vitally important benefit to the patient.
Insights
Migraine-stroke diagnosis can mask other serious conditions like arterial dissection or endocarditis. Prompt recognition of underlying causes is vital for effective patient treatment and improved outcomes.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroscience
Background:
- Migraine-stroke is a clinical diagnosis where cerebral infarction is suspected in patients with migraine.
- Recent studies show an increase in research concerning migraine-stroke.
- Accurate diagnosis is crucial for appropriate therapeutic interventions.
Observation:
- Five patients presented with a clinical diagnosis of migraine-stroke.
- Autopsy or subsequent clinical events revealed alternative etiologies for cerebral infarction in all five patients.
- Identified causes included arterial dissection, marantic endocarditis, and generalized atherosclerosis with diabetes.
Findings:
- Migraine-stroke syndrome can be mimicked by diverse and significant underlying pathologies.
- Arterial dissection was confirmed in three patients, one via autopsy.
- Marantic endocarditis, missed on initial echocardiograms, was confirmed in one patient via autopsy.
- Generalized atherosclerosis and diabetes were identified as the cause in one patient.
Implications:
- Failure to identify the true cause of cerebral infarction can lead to missed therapeutic opportunities.
- Accurate etiological diagnosis is essential for implementing life-saving treatments.
- This highlights the importance of considering differential diagnoses beyond migraine in suspected stroke cases.
