Abstract
In “Teaching NeuroImages: Multimodality imaging of carotid web,” Renard et al. presented representative images of a carotid web identified in a 52-year-old woman presenting with an ipsilateral acute middle cerebral artery infarction on 3 modalities: Doppler ultrasound, CT, and magnetic resonance angiography. In response, Dr. Sharma discusses the relative strengths and limitations of different modalities in identifying carotid webs. Dr. Sharma notes that in an ongoing study of high-resolution MRI in patients with significant symptomatic carotid stenosis, carotid webs were identified in about 22% of cases, but that the role of such webs in cryptogenic stroke remains unknown. In “Teaching NeuroImages: Multimodality imaging of carotid web,” Renard et al. presented representative images of a carotid web identified in a 52-year-old woman presenting with an ipsilateral acute middle cerebral artery infarction on 3 modalities: Doppler ultrasound, CT, and magnetic resonance angiography.
