Insights
A young boy experienced a stroke during a run due to a carotid artery dissection. This case highlights a rare cause of stroke in adolescents, emphasizing the need for prompt diagnosis.
Area of Science:
- Neurology
- Vascular Medicine
- Pediatric Stroke
Background:
- Cerebral infarction in adolescents is uncommon.
- Athletic exertion can precipitate vascular events.
- Internal carotid artery dissection is a potential cause of stroke.
Observation:
- A 13-year-old male presented with a left temporal lobe infarction.
- The event occurred during a 400-meter run.
- Magnetic resonance angiography revealed abnormalities in the left carotid and middle cerebral arteries.
Findings:
- Segmental narrowing of the left supraclinoid internal carotid artery (ICA) was observed.
- A duplicated left middle cerebral artery (MCA) was identified.
- MR angiographic source images showed a crescent-shaped lumen in the left carotid artery, consistent with dissection.
Implications:
- This case suggests supraclinoid carotid dissection can occur in young athletes.
- It underscores the importance of considering vascular dissection in adolescent stroke.
- Early identification and management of carotid dissection are crucial for preventing further ischemic events.
Abstract:
The authors present the case of a 13-year-old boy with a left temporal lobe infarction that developed during a 400-m run. Magnetic resonance (MR) angiography showed segmental narrowing of the left supraclinoid internal carotid artery (ICA) and a duplicated left middle cerebral artery (MCA). MR angiographic source images revealed a crescent-shaped left carotid lumen, indicative of a supraclinoid carotid dissection.
