Summary
Spontaneous extracranial internal carotid artery dissection (ICAD) is a rare vascular condition that can be missed. Early diagnosis using imaging like ultrasound and angiography is crucial for effective management.
Area of Science:
- Vascular Neurology
- Diagnostic Imaging
- Cerebrovascular Diseases
Background:
- Spontaneous extracranial internal carotid artery dissection (ICAD) is an uncommon yet significant cause of stroke.
- Diagnosis of ICAD can be challenging, even for experienced clinicians, due to subtle or atypical presentations.
Observation:
- A patient presented with symptoms suggestive of dissection, including partial Horner's syndrome.
- The initial clinical evaluations did not immediately lead to a definitive diagnosis of bilateral ICAD.
Findings:
- Bilateral extracranial internal carotid artery dissection was confirmed through duplex ultrasound and angiography.
- The diagnostic process involved multiple clinical assessments before definitive imaging.
Implications:
- Highlights the importance of considering ICAD in patients with relevant neurological symptoms, even if initially subtle.
- Emphasizes the diagnostic utility of duplex ultrasound and angiography in confirming extracranial internal carotid artery dissection.
- Underscores the need for heightened clinical suspicion and timely imaging to prevent potential complications like stroke.
