Summary
A hyperplastic anterior choroidal artery, an anatomical variation, can affect stroke presentation and management. Magnetic resonance angiography aids in its noninvasive detection, crucial for patient care.
Area of Science:
- Neurology
- Radiology
- Vascular Anatomy
Background:
- The anterior choroidal artery, a terminal internal carotid artery branch, can present as an anomaly.
- A hyperplastic variant is associated with an increased risk of aneurysms.
Observation:
- A 62-year-old male presented with stroke symptoms, initially suspected as posterior circulation stroke.
- Magnetic resonance imaging revealed an acute infarct and identified several vascular anomalies, including a hyperplastic left anterior choroidal artery.
Findings:
- Magnetic resonance angiography detected a hyperplastic left anterior choroidal artery, alongside other intracranial vascular variations.
- Digital subtraction angiography confirmed significant left internal carotid artery narrowing, prompting a carotid stenting recommendation.
Implications:
- Recognizing the hyperplastic anterior choroidal artery is vital for understanding disease presentation and guiding patient management.
- Noninvasive MR angiography offers reliable detection of such vascular anomalies, avoiding risks of conventional imaging.
