title: Internal Carotid Artery Web: Doppler Ultrasound with CT Angiography correlation.
abstract: We present a case of an internal carotid web, detected on duplex ultrasound and confirmed by CT angiography. To our knowledge, this is only the third reported ultrasound case in the imaging literature. This vascular abnormality can cause a clinically significant carotid stenosis and is a risk factor for recurrent embolic cerebrovascular events. Due to small size and poor awareness among radiologists, carotid webs are often under-diagnosed on non-invasive imaging modalities. Improved awareness including knowledge of salient imaging features is useful as early diagnosis leading to appropriate intervention can eliminate the risk of future cerebrovascular events.
