Summary
A left striatocapsular infarct caused temporary right hemiparesis. Cervical MR angiography confirmed a left internal carotid artery occlusion, highlighting MRA as a valuable tool for assessing carotid artery disease.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Striatocapsular infarction, a type of ischemic stroke, is often linked to carotid artery occlusive disease.
- Transient hemiparesis can be a presenting symptom of significant cerebrovascular events.
Observation:
- A patient presented with transient right hemiparesis due to a left striatocapsular infarct identified via MRI.
- Cervical MR angiography (MRA) was performed concurrently to evaluate the carotid arteries.
Findings:
- MRI confirmed a left striatocapsular infarct.
- Cervical MRA revealed a left internal carotid artery occlusion, subsequently verified by contrast arteriography.
Implications:
- This case underscores the association between striatocapsular infarcts and carotid artery disease.
- MRA is a noninvasive and effective method for evaluating cervical carotid arteries in stroke workup.
- Integrating MRA with MRI enhances diagnostic capabilities for cerebrovascular occlusive disease.
