Cryptogenic Stroke Secondary to Rare Carotid Web?

Area of Science:

• Vascular neurology
• Radiology
• Neuroimaging

Background:

• Carotid web (CW) is an endoluminal shelf-like projection at the internal carotid artery origin.
• It is an increasingly recognized cause of cryptogenic ischemic stroke, particularly in younger individuals.
• Distinguishing CW from atherosclerosis is critical for appropriate management.

Observation:

• A case of ischemic stroke in a healthy young man was attributed to a carotid web.
• Computed tomography angiography (CTA) was essential for detecting this vascular abnormality.
• The imaging features and clinical presentation of CW differ from those of atherosclerosis.

Findings:

• Carotid web is a distinct anatomical entity.
• It presents as a potential cause of cryptogenic stroke.
• Diagnosis requires advanced neuroimaging techniques like CTA.

Implications:

• Accurate diagnosis of carotid web can guide targeted interventions for cryptogenic stroke.
• Considering CW in young stroke patients without traditional risk factors is vital.
• Improved understanding of CW pathogenesis and imaging may reduce stroke recurrence.
