Patient with co-existing intracranial artery stenosis and extracranial carotid LRNC developed recurrent stroke. An example for a 63 years old male patient who had atherosclerotic plaque with lipid-rich necrotic core in the left extracranial carotid artery bifurcation (white arrows on A [T1 weighted (T1W), T2 weighted (T2w) and time-of-flight (TOF)]) and intracranial artery stenosis (white arrow on A [MRA]). After a year of follow-up, a new acute infarction was detected in the left hemisphere (white arrows on B [diffusion weighted imaging (DWI), T2-FLAIR and T1w])
