Carotid web, a form of fibromuscular dysplasia, involves a thin, membrane-like tissue in the carotid bulb that can cause thrombus formation and is linked to cryptogenic ischemic stroke. Diagnosis typically relies on detecting a shelf-like filling defect in digital subtraction angiography or 3D-CT angiography. We report a case of the symptomatic carotid web that could not be diagnosed using DSA or 3D-CT angiography due to a lodged thrombus but was successfully identified through carotid ultrasonography.

Article Synopsis
  • * A brain biopsy confirmed the diagnosis of acute disseminated encephalomyelitis (ADEM), specifically its aggressive form called acute hemorrhagic leukoencephalitis (AHLE).
  • * Treatment with corticosteroids resulted in full recovery, emphasizing the need for awareness of AHLE in older patients and the potential for related eye conditions like retinal vasculitis.

Objective: Recent studies evaluating plaque protrusion at carotid artery stenting (CAS) using optical coherence tomography showed not a few cases of plaque protrusion when using double-layer micromesh stents. We report a case of symptomatic internal carotid artery (ICA) stenosis with at-risk unstable plaques in which CAS was successfully performed using a stent-in-stent technique by the combined use of a closed-cell stent and a dual-layer micromesh stent.

Case Presentation: An 87-year-old Japanese man with dysarthria and right hemiparesis was diagnosed with atheromatous cerebral embolism caused by severe left ICA stenosis on MRI and DSA.
