Background and Purpose: Carotid webs are intraluminal filling defects at the carotid bulb which are considered rare, though possibly underappreciated entities with recent studies demonstrating a likely casual association with ischemic stroke. The purpose of the study is to describe our recent experience with clinical and imaging manifestations of carotid webs., Materials and Methods: A retrospective review of CTA neck studies in all adult patients presenting to our institution during the 19-month study interval was performed to determine the presence of carotid webs. Subsequent chart review of these patients with webs was performed to assess their clinical history and to obtain demographic detail., Results: A total of 14 patients were identified with carotid webs in the study population. The mean age of patients with webs was 42.1 years (range: 28-54), consisting mostly of African Americans (86%) and females (64%). Ten (71%) of web patients had a history of ischemic stroke, each ipsilateral to the side of web, and at least four of these patients had recurrent ischemic stroke., Conclusion: We provide one of the largest sample sizes of webs gathered in a single study. Given its association with ischemic stroke, carotid webs should be assessed for in all patients presenting with ischemic stroke, especially younger African Americans., (Copyright © 2018 Elsevier Masson SAS.

The article presents a case study of a 69-year-old female patient who had a left posterior cerebral artery infarct in whom progressive Wallerian degeneration (WD) of the splenium of the corpus callosum depicted on magnetic resonance imaging (MRI) was misinterpreted as new infarction or neoplasm. It discusses the use of magnetic resonance spectroscopy, perfusion MRI, diffusion tensor MRI, and serial imaging in establishing the correct diagnosis.
