OBJECTIVE: Illustrates the importance of differentiating limb-shaking transient ischemic attack (LS-TIA) from focal seizures and carefully selecting patients for intracranial stenting. BACKGROUND: LS-TIA is associated with severe carotid stenosis or occlusion, often precipitated by cerebral hypoperfusion. A case study of 313 patients with symptomatic intracranial artery stenosis/occlusion reported 11% with LS-TIA. In our literature search, we did not find any other cases of successful treatment of LS-TIA with an intracranial Wingspan stent. DESIGN/ METHODS: A 66-year-old woman with a history of atrial fibrillation on anticoagulation, hypertension, hyperlipidemia and left middle cerebral artery (MCA) stroke followed by a left internal carotid artery (ICA) endarterectomy presented with transient repetitive involuntary movements (TRIMs) over her right upper and lower limbs. She described episodes of numbness followed by TRIMs over the right side of her body lasting for 1 to 2 minutes. TRIMs occurred only while standing and usually resolved on sitting or lying down. RESULTS: Conventional angiogram showed severe stenosis of left supraclinoid ICA and proximal MCA. Brain single photon emission computed tomography scan showed impaired vascular reserve in the left MCA territory. An ambulatory electroencephalogram captured TRIMs without epileptiform discharges. She continued to have symptoms with no improvement over a period of 3 months on maximal medical management. She underwent successful endovascular treatment with the Wingspan stent system in the left M1 segment and terminal ICA. Following the revascularization procedure, her symptoms resolved. CONCLUSIONS: It is vitally important to differentiate LS-TIA from focal seizures. This is the first documented case report of complete resolution of LS-TIA symptoms following an intracranial Wingspan stenting.
