Summary
Pure sensory stroke (PSS) can sometimes precede a large middle cerebral artery (MCA) infarction. This association may be linked to carotid artery occlusion, highlighting a critical warning sign for severe stroke.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Pure sensory stroke (PSS) is typically associated with small lacunar infarcts.
- The presentation of PSS can sometimes be misleading, masking underlying cerebrovascular pathology.
Observation:
- A patient with hypertension and diabetes presented with PSS symptoms.
- Initial CT revealed a subcortical infarct in the middle cerebral artery (MCA) territory.
- The infarct rapidly expanded to a large hemispheric infarction with neurological decline.
Findings:
- Doppler ultrasound identified ipsilateral carotid artery occlusion and contralateral severe stenosis.
- The findings suggest a link between PSS and extensive MCA infarction in the context of severe carotid disease.
Implications:
- PSS may serve as an early warning sign for impending large MCA territory infarcts.
- Aggressive evaluation and management of carotid artery disease are crucial in patients presenting with PSS.
- This case underscores the importance of considering severe cerebrovascular disease in atypical PSS presentations.
