Idiopathic internal carotid artery (ICA) vasospasm is a rare cause of ischemic stroke. Its pathophysiology remains unclear and diagnostic and treatment protocols are yet to be defined. A 45-year-old male, presenting with recurrent transient dizziness, blurred vision, and speech disturbances, was diagnosed with recurrent ischemic stroke caused by bilateral ICA and middle cerebral artery (MCA) vasospasm, and the vascular ultrasound and imaging techniques have grabbed the reversible changes in a short time. This case underscores the importance of considering idiopathic ICA vasospasm as a potential cause of recurrent ischemic stroke, even in the absence of common diagnostic markers. The case also indicates the possible, albeit rare, involvement of the MCA in this condition. Therefore, it is crucial to maintain a high index of suspicion for idiopathic ICA vasospasm in similar clinical presentations and to explore more inclusive diagnostic criteria.
